dasparkhotel

Ever wanted to sleep overnight in a sewage pipe? Well, now you can thanks to dasparkhotel at Radl Park in Ottensheim, Austria. Yes, reservations are required, but rates are optional.

The pipes contain a double bed and has electricity. Bathrooms are available nearby, but despite the prior functions served by the pipes they no longer are hooked up to running water. The doors have a lock with code sent upon reservation. Rates are not set; "customers leave a Euro amount that they can afford and with which they wish to support our project."
