Duri and Luzia's place is almost perfect. The apartment is as advertised, very spacious, the bathroom is luxuriously large, overall plenty of room even for longer stays. The place was pristine clean, all of the furniture is of high quality, you can see attention to detail everywhere (especially the bed and mattress is probably one of the best I ever slept on). I stayed with Duri and Luzia for 2.5 months, as I was searching for a permanent accommodation in Zurich. The apartment was (apart from a bit small shared kitchenette if I wanted to cook regularly) perfectly fine for a long stay, it was equipped with everything I needed, shared washing machine and dryer were a big plus, bi-weekly cleaning service was also very nice. The neighborhood is calm and quiet, but still near the center of Zurich (tram stop is nearby, walk to the center is perfectly possible too). Duri and Luzia were extremely nice hosts, responsive, friendly and helpful.
