Katja’s apartment was modern, clean and cosy. The apartment was ideally located in the Mitte area, close to transportation and many nice restaurants. The Mauerpark, where lots of happenings were taking place during our visit, was some few minutes’ walk from the flat. The check-in and check-out times were flexible, which was nice. The only minus comes from the somewhat musty smell that was present in the apartment all the time, even though we kept the windows open whenever we were in the apartment. All in all, however, Katja’s flat was a very nice place to stay in.
