The apartment is lovely and in the middle of the historic pedestrian area. Two things should be noted-key pick up is not near the apartment. We had our own car and Zurich has many one way streets and it took some time to get from the key pick up to the apartment. Because the apartment is located in the pedestrian area, there is not a convenient way to drop off your bags. We were traveling with our young son and had to bring his portable crib. The parking garage is nearby (5-7 min walk), but I suggest you look it up before arrival as we spent quite some time looking for a garage and figuring out logistics of moving our bags. FYI parking was 45 francs for 9-24 hours.
There is a wonderful restaurant, August, just down the street as well as many cafes and bakeries. It is a really great location if you want to be near the historic sites and the river and quiet. It is also near a Lidl and Coop for groceries.
It was warm (30C) when we stayed and only 1 fan in the apartment, so the living room or the bedroom was cool, but not both at once. This is something to consider if you have someone sleeping on the pull out couch.
The kitchen has all utensils you would need for a short stay and the apartment was very clean.
Communication with Tania was easy and she responded quickly.
