Maybe your hotel fantasy is a little darker.  If so, try the coffin room or the padded cell room (pictured to the right), where for 80 Euros you can spend the night in a German padded cell.

However, if you need a room closer to the fantasy track, try what must be jamiroquai's favorite room, #23, the upside down room.  Even if your fantasy borders on masochistic, this Berlin hotel provides you with such outlets as the two Lions room, complete with dual sleeping cages.

Sounds like there is something for everyone at this German themed hotel.
