I spent a great week in Katja's apartment. The room is bright and quiet, the bed is very comfortable and the whole apartment is beautiful. Katja is a perfect host: she makes you feel comfortable about sharing the apartment with her, gives local tips when needed and goes out of her way to accommodate your needs. During my stay there were some minor works in the apartment and she warned me ahead and made sure I was not disturbed by them. The apartment is in a charming residential area, full of young couples with kids, nice cafes, restaurants, and very well communicated. Mind you: it is in a fourth level with no lift.
