Boise, Idaho, has been called the best place for millennials to live in the US. I spent 4 days there, and a walk through downtown makes it clear why it's so popular.

In New York City, the average commute is more than double that of Boise's at 40.8 minutes. In San Francisco, it's 32.8 minutes.

In 2019, Boise was ranked the best place to live for millennials as well as the best US city to buy a house. And it has a burgeoning tech scene.

I recently spent four days in Boise, exploring downtown and other areas, interviewing local business owners, and chatting with locals.

"In the last 10 years, Idaho's economy has become more diverse, which can easily be seen in the boom downtown," Wes Jost, senior vice president and manager of Zions Bank's Idaho Commercial Real Estate Group, told me. "New people and businesses are continuing to relocate to Boise, placing our area in growth mode for the last six to seven years."

That boom was clear during my visit.

Boise is a city of just of 229,000 people, but throughout my time there, downtown was bustling with people walking and biking the streets, grabbing a coffee in the plethora of trendy cafés, and even sitting outside in the sun on a brisk November day.

I spotted several colorful murals in alleyways and on the sides of buildings.

Boise has a Basque community of about 16,000, one of the largest in the US.

The Basque people come from the western foothills of the Pyrenees Mountains on the border of Spain and France. They have their own distinct Basque language.

On my last night in Boise, a Friday night, I stopped into Bardenay for a drink. Inside, I found a boisterous atmosphere, with people of all ages filling up the large space.

I paid $7.50 for a tasty Huckleberry Lemon Drop cocktail, which is made with Bardenay lemon vodka, Triple Sec, fresh-pressed sweet and sour, and handpicked Idaho huckleberry puree. And at $7.50, the price was a welcome relief from New York City, where I live, and where cocktails can easily go for double that price.

The restaurant-distillery serves a variety of dishes, from sandwiches and burgers to tacos and sea bass gnocchi.

10 Barrel Brewing Company originates in Bend, Oregon, and opened its Boise location in 2013.

Boise Brewing Company on Broad Street opened in 2014 and brews at least 14 beers — from blonde ales to stouts to IPAs — and one cider. It hosts trivia nights, live music, fundraisers, and "brewery yoga" on Sundays.

Other local breweries include Barbarian Brewing, Payette Brewing Company, White Dog Brewing Company, and Woodland Empire Craft Ale.

You can choose from more than 40 beers on tap that start at $2 for a half-pint and $5 for a pint.

Owner Dave Krick said he got lucky that he picked Bittercreek Alehouse's 8th Street location back in the '90s. Today, 8th Street is clearly one of the most happening streets in the area.

"I don't think I could've predicted the future of where we landed, but I just loved downtown Boise," he told me. "I loved 8th Street cause I grew up down here and it's where I wanted to center my life. And lucky me, so did a lot of other people."

The premise of his business was simple, he says: "I love beer. I wanted to make a place that people could come and discover good beer ... in those days, it was much more of a geek thing than it is today."

I stopped in for lunch one day and got the Huntsman Burger, which comes with Gloucester cheddar and stilton bleu cheese, pickle, onion, tomato, applewood smoked bacon, a side of housecut organic Idaho potatoes, and a draft cider (I'm not much of a beer person).

The burger was $15.50, which is certainly not the cheapest burger to be found in Boise, but it was perfectly juicy and worth every penny.

It serves 20 ciders on tap, including Meriwether ciders and ciders from all around the world.

I tried their $7 hot mulled cider, which was very effective in warming me up on a brisk November evening.

On my last night in Boise, I went from the Bardenay distillery to Press and Pony, a dimly lit cocktail bar with a speakeasy vibe.

My last stop of the night was the Spacebar Arcade, a retro underground bar where you can drink cheap beers while playing Pac-Man and pinball.

On the same Main Street block are Cactus Bar, which claims to be the oldest bar in downtown Boise, and Pengilly's Saloon, which has $2 well drinks on Tuesdays.

The river is surrounded by a 25-mile stretch of tree-lined trails called the Greenbelt.

One morning, I spent about half an hour strolling down the Greenbelt from my hotel to the heart of downtown, and I passed several joggers, cyclists, and people walking their dogs.

I passed by an indoor cycling and yoga studio called UpCycle Studio, which has a kombucha and cold brew bar.

Also downtown is a PIVOT Lifestyle + Fitness by KA, a fitness center founded by Kristin Armstrong, a local three-time Olympic gold medalist in women's cycling.

There's also a Crunch Fitness west of downtown and a Pure Barre studio near the river.

The city has a bike rental program, but most people appeared to be riding their own bikes.

Another common mode of transportation was via e-scooter from two of the major companies, Bird and Lime.

When it opened, the Whole Foods was seen as a competitor to the beloved Boise Co-Op, which is just north of downtown.

But the Co-Op seemed to be thriving when I visited — and in fact, it opened a second location in the Boise suburb of Meridian in 2015.

The Fowler opened downtown in 2018.

"We get a mix of residents who are new to Boise and those relocating downtown from other parts of the city," Casey Lynch, the CEO of Roundhouse, the Fowler's developer, told me. "As a fast-growing city, we see people moving from all over California, Seattle, and other expensive coastal markets."

"The condos are quite expensive and that's led to a lot of new apartment projects with plenty more in the works," he said.

In the Fowler, the average rent of a one-bedroom is just under $1,500 per month. That's about $500 more expensive than the median rent of a one-bedroom in Boise, which is $980, according to Zumper.

More than 1,000 residential units are in the planning stages in downtown Boise, The Idaho Statesman reported in May.

There are more than 20 coffee and tea shops downtown, according to the Downtown Boise Association.

One of the places that epitomizes this scene is Form & Function, a hip, minimalist coffee shop on the ground floor of the Fowler that opened in January 2018.

Floor-to-ceiling windows let in plenty of sunshine.

A local I met told me Flying M was considered a "safe space" for LBGTQ people.

Some of the customers seemed to be friends meeting to catch up, others appeared to be working on their laptops, and others still were just reading the newspaper over coffee.

My latte and snickerdoodle cookie came out to less than $5 — half the price of most coffee shops in New York City.

Eater named it one of the 25 best restaurants in Boise.

It sits in the corner of the ground floor of the Fowler next to the Form & Function coffee shop.

The Wylder was opened by David and Lizzy Rex after they moved from Santa Monica, California, in 2017.

I had dinner there one night and was surprised to find the restaurant was packed on a Wednesday evening. It felt like a cool New York restaurant, except less crowded and also somehow cozier.

I ordered their most popular menu item, according to Yelp: the honey badger pizza, which costs $18 and comes with Italian sausage, ricotta, caramelized onions, and spicy honey. It was one of the best pizzas I've ever had.

David Rex, who used to spend summers in Idaho as a kid, told me the Wylder's pizza dough takes 48 hours to make and they use the highest quality flour and ingredients they can find.

At the recommendation of several locals, I had breakfast there one morning. I'd been warned that the lines can be out the door and down the block. Even on a Thursday morning, I had to wait for almost 10 minutes before getting a seat at the end of the bar.

I ordered a drip coffee and Eggs Benedict with a side of home fries. The portion was surprisingly large and the hollandaise sauce was rich and creamy.

My meal would've come out to less than $15, but I didn't even get a chance to see my receipt, because the elderly man next to me — a Korean War veteran — ended up sneakily paying my bill after we chatted throughout the meal.

Jelli CEO Mike Dougherty told me they chose Boise as an alternative to the "high costs and sort of broken nature of some of the economics" in the Bay Area.

"One of the things that we noticed when we were looking at Boise was how we really enjoyed the downtown voices, specifically the culture there," Dougherty said. "It felt very progressive. There are tons of fun little farm to table restaurants, great coffee shops ... it reminded me a little of Austin maybe 10 years ago or Portland or something like that."

Boise is the longtime home of Hewlett-Packard's imaging and printing group, which introduced the HP LaserJet printer.

After registered nurses, the most in-demand occupation in Idaho is software engineer.

I saw secondhand book shops, a healthy dog food store, a store that sells artisan roasted nuts, chocolate, clothing boutiques that sell clogs and Free People dresses, and chains like North Face and West Elm.

Beyond the dynamic restaurants, bars, and shops, the people I encountered downtown were all incredibly friendly — almost "annoyingly friendly," as Bittercreek owner Dave Krick jokingly put it — and eager to chat.

And it's worth noting that the mix of entertainment, dining, and wellness options is extremely well-tailored to the millennial lifestyle — especially since downtown is so walkable. Plus, the prices I paid for coffees, meals, and drinks were all a welcome reprieve from NYC prices; the city's relative affordability is also a good fit, financially, for a generation as cost-conscious as millennials.

Coming from New York City, I can certainly see the appeal of Boise: it's a manageable size, yet it has everything you need. And I don't think I've ever visited another city where the residents — perhaps partly because many of them came from big cities like Los Angeles and Seattle — are so unabashedly delighted to live there.
