Fantastic location! Just a couple of tram stops away from Zurich's main district, and there were supermarkets, a bakery and several restaurants around the apartment if you don't want to wander far. We could also hear the bell tolling from the church in the evening :)
The apartment is large, comfortable and clean. There were lovely plants everywhere which gave it a homely feel and enough room for 6 people! (We had 5 so it was very comfortable.)
