Hotel built from old drain pipes
Dasparkhotel, that’s the name of this unique hotel built near Essen, Germany. You can book a “room” here from May to October, and you will get a full headroom, double bed, storage, light, power, woolly blanket and light cotton sleeping bag.
For how much? Well, the hotel is run under the policy of “Pay as you wish”, so no fixed costs, but only how much are you willing to contribute in supporting this project.
The only downside of this experience is that the showers and toilets are in the surrounding public places (other drain pipes).
