From the looks of it, The Michelberger Hotel in Berlin is definitely not your average tourist hotel. For one thing, instead of plain old wallpaper, how would you like your room's wall covered in books?! Imagine if the book you wanted to read was the one stuck at the top corner. Now there's a challenge. Gotta love the creativity! I also had to share their amusing "do not disturb" sign. People can be so clever.

The Michelberger Hotel website is also a really impressive treat to visit.
