Would you sleep here? Open air hotel 'room' is bed on top of a mountain

There aren't many hotels that have zero stars that have guests competing to make a booking - much less those hotel rooms that don't even have a toilet.

But this open air hotel in Switzerland has had hundreds of people clamouring to stay - despite the fact it has no ceiling, walls, or indeed any facilities.

The Null Stern hotel is, in fact, just a double bed, with a nightstand and lamps, perched on the top of a mountain.

But despite the fact that your stay can be cancelled due to bad weather, every night available at the hotel is booked up.

For the cost of 250 Sfr (£191) per night, guests are immersed in nature at 6,463 feet above sea level in the Graubünden mountains.

The design of each 'room' is very minimal with just a double bed, nightstand and lamps.

Though the closest bathroom is a public toilet a 10 minute walk away, guests will have a butler on hand who will welcome them and serve them a salami sandwich and coffee in the morning.

This isn't the first quirky property from Null Stern founders Frank and Patrik Riklin. The name of the company translates to mean 'zero stars'.

Their slogan, 'the only star is you' suggests this hospitality group strives for zero stars. However, playing with words, this new Alps venture lets guests sleep under millions of stars.

Really the Riklins define themselves as conceptual artists that use hotels as their means of expression. Hence, their previous endeavour, which saw them transform a former nuclear bunker in Swiss city Teufen into a hotel.

Daniel Charbonnier said: "Even though this version is radically different from the first one in the nuclear bunker, the essence and the spirit of the concept remains the same: to put the guest at the centre of the experience and to focus on the intangible by reducing everything else to the minimum."
