Stayed here one night before flying out of Zurich. The location is great -- can hop on a tram and be in town within 10 minutes or the airport in 25 minutes. The apartment was very clean. We had an issue with one of the outlets before checking out but the owner was responsive to get it fixed. Unfortunately we lost our travel adapter due to issue.
The con is this apartment is very close to a busy road. During the day it was very noisy with traffic/tram noise and church bells. I'm a very light sleeper so I was nervous I wouldn't get any sleep. At night with my sleep aid fan app I slept like a baby. I would recommend sleep aid app or ear plugs if you're a light sleeper.
