We were a family of 5 for two nights - first time in Zurich - and this was the perfect place for us. 4 comfortable beds in 3 rooms with 1.5 baths and small kitchen. Very clean and simple. Apartment is on the fringe of all the tourist attractions, so walking distance to everything we came to see, including central city.
Tania was a great communicator and accommodated us re one or two requests we had made. Would definitely recommend.
