Zero-star-hotel: Find out why hundreds are booking a room here

If an ideal hotel means silence, opulence or even a roof then this swiss resort may not be your calling. Riklin brothers have a different spin on hospitality - one where your hotel room has no walls or ceiling - essentially a Zeo-Star-Hotel, which is what its name Null Stern Hotel literally means.

The Swiss conceptual artists' hotel room is essentially a double bed on a platform, with two bedside tables and lamps. There are no walls, ceilings, or doors to provide any privacy or shelter. The suites, which come with butler service offering drinks and breakfast, will be available from July 1 to September 18. The price for an imperfect night's sleep is 325 Swiss francs ($338).

The intention is to make guests think about the problems in the world, the twin brothers said, and inspire them to act differently.
