Das Parkhotel

Das Parkhotel is, incredibly, a set of hotel rooms built inside of drain pipes. The "hotel" is located in a public park, where bathrooms and cafeteria are close at hand. Reservations are made online, and payment is described as "pay as you wish": guests leave an amount they can afford inside the room when they leave.

It was conceived and designed by Andreas Strauss, and is located in Ottensheim, Austria.

I will stay there one day.
