This is a lovely flat. Its large - larger than I expected from the photos, and larger than I thought it could be because of the central location.
The key pick up/drop was very easy and no waiting time at all.
I visited during a heatwave and was so glad that there was a pedestal fan!
Lots of windows for air/light and I couldn't find a single reason to fault it.
Not sure why some reviewers have found the restaurant on the ground floot to be a problem. The restaurant has very limited and sensible working hours, are not at all noisy and there are no smells coming up to the room at all.
If I find myself back in Zurich I would definitely look to stay here again.
