Parkhotel

If you happen to be looking for a place to stay in Oppensheim (near Linz in Austria), why not consider the parkhotel? The rooms are made out of standard concrete drainage-pipes and are situated in a public park. The facilities of the hotel are existing local amenities: you can shower in a nearby swimming pool, and have breakfast at the local gas station.
And if you wonder about the payment: the hotel functions on the principle of "pay as you wish": paying what you can afford - or paying what you think your stay was worth.
