We would never think of sewage pipes as a possible structure for a hotel room, but these ones are clean, modern, and functional. Three drain pipes have been converted into a hotel that is located in a public park. They are part of the Das Park Hotel, experimental hotel in Austria.
The rooms at the Park Hotel feature full headroom, double bed, storage, light, power, sleeping bags, and blankets. The main complex includes toilets, showers, mini bar, cafeteria etc. The rooms are secured by a key code, so the guests' personal belonging are safe. Probably the most experimental aspect of this hotel is that it operates on the "pay as you wish" system. The customers leave an amount that they can afford and with which they choose to support the project. What are your thoughts? Would you stay at this hotel?
