This is a professionally run hotel and as such offers all the amenities that you'd expect, including A/C. They do a very good job here, with friendly staff and clean rooms. And because they waive the AirBnB-fees, the offer is fairly competitive for close to downtown Zurich. So I'm I have only good things to say; but as an Airbnb-host myself, I'm just a bit puzzled with this offer. In any case, stay here, you won't regret it.
