Das Park Hotel, Linz, Austria
This doesn’t just looks like a humongous tube. Guess what? It is in fact a humongous tube and beyond that, a humongous tube that you can sleep in! This is actually a concrete cylinder that is located in a park in Austria. Well, that is silly, right? Not necessarily. This can be the innovation of the century!

This cylinder contains a comfortable bed, blankets and even power! It is like high tech camping. We do recommend that if you Austria in the winter months that you bring some of your own warm blankets to supplement their supplies. Other than that, take in this hostel and visit the surrounding restaurant, café… and, of course, toilets!
