You don’t need to sleep in a tent to enjoy the great outdoors. Just rent out a hotel bed under the stars. This summer and fall, a pair of artists is opening a hotel that has no walls or ceiling on a mountain in Graubünden, Switzerland, Travel + Leisure reports.

The wall-less hotel room comes courtesy of the creators of the Null Stern Hotel (or “zero stars”), a temporary hotel that opened in a nuclear fallout shelter in 2009 as an art installation. It was later converted into a museum about the experience, but the mountaintop hotel revives the idea—albeit in a far more luxurious manner. Well, luxury enough that there’s a nice bed and a few lamps. Going to the bathroom requires a 10-minute hike to a public facility, and the reservation could be canceled at any time due to inclement weather. You do, however, get a salami sandwich and coffee delivered by a butler in the morning.

The artists behind the project hope to open more beds in other Swiss valleys by working with regional tourist associations. Their motto is both flattering and terrifying: “Null Stern Hotel: Where the only star is you.”

Reserve it for roughly $255 a night.
