I stayed at Diana' s for a month during my work trip. The flat is equipped with everything needed for a shot or long stay and the room is very comfortable and quiet. The flat is bright across the day and the living room gets light even in winter. You can reach the city center within 15 min by tram or have a lovely walk across the lake. There are lots of amenities around and supermarkets within 4 min walk. Really recommend it if you want to be in the heart of Zurich but still away from the hustle and bustle of daily life.
