I traveled to Zurich for only one night with my teenage son. This apartment was wonderful - very clean, and with so many amenities! Everything you could need was here. Kitchen with oven, fridge, microwave, coffee maker, dishes, cooking ware, etc. We were able to save money by cooking in the apartment after visiting a grocery store only a few blocks away.
Bathroom was very clean, plenty of hot water, great water pressure. Bed and sofa were both comfortable for our jetlagged bodies.
Hosts were gracious and quick with responses, and even provide tips for where to eat or visit. They provided coffee, tea, and some snacks and drinks, as well, such nice touches.
(The apartment is on the ground floor, so bring ear plugs or white noise if your sleep is interrupted by cars passing or conversations. This is no fault of the host, just something to note if you are a light sleeper like me, but I was totally fine with ear buds playing white noise.)
I'd definitely recommend this apartment to anyone staying in Zurich.
