I stayed in Klaus' place for almost two weeks and have no complains. The house is extremely clean and bright, very well decorated and the room is wide and the beds confortable. The building is very interesting, I loved it, it's in a residencial area, calm and quiet, but very close to metro and train stations (2min walk), the localization is perfect. Klaus is an amazing host, very friendly, and gives you all privacy needed. I highly recommend this place.
