Niels's place is very nice, everything was clean and welcoming. Communication with Niels was always easy and quick, and he was always very helpful. The flat is located in a nice area, very easy to get to with public transport or car, and there are many restaurants and supermarkets in the area. Wifi was great. The only issue I felt was that the apartment is a little small and cramped (even though we are both two small people). But if this doesn't bother you than I would recommend this place to anyone visiting Zurich!
