The stunning Swiss Alps 'hotel room' without walls is opening a new location -take a look

One open-air hotel, called Null Stern, eliminates walls and a roof altogether. Staying there is a lot like camping. Located in the middle of the Swiss Alps, it only features a bed with linens.

In German, the hotel's name translates to "zero stars."

"The star is not the hotel but each guest," the hotel's co-founder, Daniel Charbonnier, told Business Insider. "We got rid of all the walls, and the only thing left is you and your experience."

Null Stern launched with one bed in July 2016, and it opened its second in early June on the Göbsi summit in Appenzell, Switzerland.
