Our family of 5 stayed for 2 nghts. The flat is not terribly large but is really very well located (walking distance to the train station, old town, river/lake and amidst numerous shops, restaurants and nightlife). For five people to sit to hang out together in the flat you need to use the terrace, however for this you need the weather to cooperate both at the time and for some time prior as the seat cushions would need time to dry out. As we were not so lucky with the weather we did not spend much time in the flat apart from sleeping and simple self catered breakfast of bread, cheese, ham, yogurt, etc. This worked out ok as we enjoyed exploring Zurich on foot.
