There’s a fantastic looking hostel in Bonn, Germany, called BaseCamp, that’s made up of camping trailers parked in a giant warehouse close to the city center. Lodging is not limited to campers. They also offer a railway sleeper car, VW camper buses, even a former East German Trabant with a tent on top.
The hostel has a 120 bed capacity and rates range from $32 to about $100 per night.
