From a lodge sculpted from ice to one made from metal sheets, it seems like there’s an infinite number of offbeat hotels that re-think the traditional B&B.

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.

Take a look below.


Located 6,463 feet above sea level, the first Null Stern 'room' sits in the Swiss Alps. It costs about $210 a night.

To install the bed on the mountains, a construction crew flattened the land.

The hotel has no walls, roof, or bathroom — only a queen bed with a pair of nightstands and lamps. A public bathroom is about a five-minute walk down the mountain, Charbonnier says.

It offers panoramic of the mountains and the stars at night. "Switzerland becomes the hotel," he says.

But like a normal hotel, room service (in the form of a personal butler) comes to guests.

... and prepares guests' meals, including dinner and breakfast in bed.

The new room, which also features a queen bed, is located on the Göbsi summit. That's nearly 4,000 feet above sea level.

Unlike the first location, this one features a "television without a remote control and only one exclusive channel," according to a press release from Null Stern. The butler delivers the day's news headlines, weather forecast, and other anecdotes through the frame.

Though the new "room" opened in early June 2017, Charbonnier says Null Stern will not start taking reservations until 2018. Fortunately, if there's bad weather, guests can cancel their reservations last-minute.
