5. Das Park, Austria
If you’ve wondered what it would feel like to live in concrete drainage and sewage pipes, you needn’t wonder anymore. That’s because the Das Park hotel in Austria houses cylindrical accommodations made of repurposed drainpipes. The interior of the hotel is fairly simple and effective. There is an electronic outlet, storage space present under the bed, and a foam mattress on a slatted frame. The key code for a room can be requested by guests online and they can pay what they wish, but they can only stay there for a maximum of three days. The restrooms and showers aren’t located inside the accommodation.
