We did not get to meet Chris but his friend Blanca gave us the key. The location is indeed very convenient, a few meters away from the tram and train station which is directly connected to the airport. The apartment was spacious enough for 3 people, and felt homey and really clean. Quiet neighborhood. Our stay in Zurich was the most relaxed of all our Europe stops mainly because of this apartment. Thank you very much, Blanca and Chris!
