We had a great stay. The location is absolutely perfect. I cannot imagine a better location in Zurich. And the appartment was clean and comfortable. We would happily stay here again.
The street can be a bit noisy at night, so if you have earplugs that's the best.
Also the check in instructions were a bit confusing as to what the location and apartment number were. And there is no Nuki keypad that I could see, so you'll need to download the app to your phone to access the apartment and pick up the physical key.
