Weird Drain Pipe Hotel
Dasparkhotel is a concept hotel by Andreas Strauss in which guests stay in converted drain pipe sections that are placed in a city park. Made out of sewer pipes, it holds basic accommodation with a bed for two and a light source, with ample space to store your luggage and use your electrical appliances.
There are currently two hotels, one near Essen, Germany, and another in Ottensheim, Austria. Dasparkhotel accepts online reservations from May to October and is sliding scale.
