Carla's apartment is very nicely maintained, neat and tidy place. It is very central in Zurich and within walking distance to lake and opera house. Very well connected to public transport as well. There is a direct tram to airport, and central Zurich station.
Carla is very friendly, helpful and approachable is organising things.
I had a wonderful time during my stay and would recommend the apartment to anyone visiting Zurich for leisure or business.
