Sofia was a very nice and polite! If you need anything during your stay the hostess will help you. The apartment is in a very good location, so you can reach everything in the centre of Zurich within minutes and have a nice walk in the Old city.It is also vey fast to reach the main train station (5-7 min walk). I would only advise to take your own hairdresser if you need one.) I enjoyed my stay!
