We really enjoyed our stay at Katja's house. The location is superb since it is really close to the city center (only 5min walk to the center); only downside is the construction site at the other side of the road (makes some noise during the weekdays). There is a private underground parking which is really convenient when being so close to the city center! The check-in/check-out were both very easy, and the communication before, during and after our stay was super friendly and spotless. Make sure to respect the check-out time of 10h in the morning though since the cleaning ladies are already present at 10h05. The apartment is perfect for couples traveling with children like us since all commodities are available (cribs, high chairs, and even toys etc.). The WiFi in the apartment is very fast. There is a balcony almost entirely around the apartment, which is great.
