Berlin’s Propeller Island hotel offers themed rooms ranging from the tame to the extreme. The rooms are so awesome I would not want to go to sleep--I really really wouldn’t. The Mirror Room in the Propeller Island City Lodge in Berlin really blows my mind. Maybe it was designed with “sexy” reasons in mind but I can only see awesome design.

Far too creepy for me are the coffin beds on offer, and the room with the two lion cages just puzzles me (there are also beds). And as for the upside-down room, how are you expected to get any sleep? That would just mess with your head all night--if that's a good thing. Only you can decide.
