We stayed 3 nights with Silvia, and it was very enjoyable: pleasant and quiet surroundings, near the places we needed to go to but also easy to get to Zurich center by bus. The house (in particular the bedroom, shared sitting-room and kitchen, garden) is large and comfortable, so it would also be good for a longer (week-long or even month-long) stay. Silvia is very welcoming and helpful, and the breakfast was really a plus for us!
