Inside the Palo Alto 'Facebook House' where Mark Zuckerberg lived, that's now a Mecca for wannabe-entrepreneurs

• In 2004, Mark Zuckerberg and the early Facebook team moved into a five-bed house in Palo Alto, California.
• It was run like a "frat house," and would later be made famous by the 2010 film "The Social Network."
• Today it's a haven for budding entrepreneurs and business students, and Business Insider got a look inside.

Before Facebook was a $500 billion behemoth with 2 billion users and the power to reshape society, it was just another scrappy startup.

Founded in the halls of Harvard, the Facebook founders moved west to Palo Alto, Calif. in the summer of 2004 - a relocation that was made famous by the 2010 film "The Social Network."

In those early days, the Facebook team lived and worked in a nondescript five-bed home in Palo Alto, building their fast-growing social network in a setting that one former executive likened to a "frat house." Today, the company's offices are still nearby, in Menlo Park - while the "Facebook House" has become a mecca for budding entrepreneurs and business students with dreams of following in Zuckerberg's footsteps.

Business Insider took a tour of the property to see the historical location in Silicon Valley history up close - and to meet the people living there today.
