Our stay at Sonia’s apartment was excellent. The location is perfect, close to the train station and with a lot of restaurants and shops nearby. The apartment was spotless clean and really well equipped. We didn’t have any issue with noise. We slept very well and the bed was really comfy. The best part of the apartment is that the heat is excellent, we were there in winter in really cold days and inside the apartment was really warm and cosy. We really recommend this place to anyone staying in Zurich.
