This stunning setup might look like Photoshop, but rest assured, this open-air hotel and the spectacular alpine views are all very real. The Null Stern Hotel just opened their latest venture: the ultimate minimalist hotel room that has no walls, roof, or bathroom, and is set 6,463 feet above sea level overlooking the beautiful Swiss alps of Graubünden. Although plumbing isn’t included in the stay, breakfast-in-bed and butler service are part of the deal. The price for such luxury, however, isn't cheap.
