Hotel on the top of Palais de Tokyo, Paris

There is a absolutely crazy thing going on the top of the Palais de Tokyo!!
Have you seen it? It is green, rectangular and it seems coming from another planet! Yeah, really!
I just discovered it's a HOTEL! Yeah, really!

Hotel Everland is a project by Swiss artist-duo Sabina Lang and Daniel Baumann. They are known for their Installations that deal with architecture and space.

Everland is a Hotel with only one room including a bathroom, a king-size bed and a lounge. The bounteous dimensioned room represents the subjective dream of a hotel. All Everland guests are partaking in the project.

Also the concept for operating the hotel was defined by the artists. All facets are important constituents of the artistic idea. The room can be booked for one night only, the mini-bar is fully stocked and included in the price, breakfast is delivered to the door and a record collection stands at ones disposal.

You can book online but you are going to wait until a little bit because they are fully-booked for the next 60 days!
333€ is the price for the "room".

If anybody has ever been in there, please tell us more. I'm dying to visit it.
