Null Stern (No Star) Hotel in a nuclear bunker

The name Null Stern Hotel (Zero Star Hotel) is the program: this hotel offers absolutely no comfort. It is an abandoned secret bunker, unused since the end of the cold war, which was transformed into a hotel. Obviously there are no windows, but there is no reason why there should not be any comfort. But the organizers plan to drop any kind of decoration in the room, there are simply beds, which look a bit like second had furniture from a yard sale. And there is no comfortable infrastructure like swimming pool, sauna and so on. The sanitary installations are all original, actually there is not enough warm water so a wheel of fortune determines who gets to shower with warm water. A unique chance to get the real World War III feeling.
