This is a spacious, sunny place and great when you are visiting with family or multiple people. Good value in expensive Zurich. We enjoyed the balcony and the spacious living room. It's one of the few reasonable places I found in Zurich that had 3+ beds.
Pros: great and flexible check-in (we arrived at different times and Filipa was very helpful), spacious apartment, sunny living room, safe area nice for walking, really nice balcony for a glass of wine at the end of the day, restaurants about 15mins walk away (at least the ones we found).
Cons: CHF 10-15 Uber ride to the main areas if you can't use the trams (with family, seniors, etc) and Ubers take a while to arrive, very few cafes etc nearby and even the 2 grocery stores within walking distance are closed on Sundays, the bathroom is old with old plumbing so we saw that the shower drained *really slowly* and water filled up (already informed the host), the bar's noise definitely bothers at least the people in the 2nd bedroom (close to the front door), the walls are thin which means you hear the noisy neighbors (again, for the 2nd bedroom), 4 flights of stairs so you may want to keep this in mind if you have a lot of luggage, kids or seniors.
