We had a good stay here. The real value is the location. It's in a great neighbourhood: easy to get to from the main train station via transit or foot and a quick walk to the river and many restaurants and parks. You can take the train up to Uetliberg right from the apartment or else walk up the street and hike to the top of the hill if you please. For good or for evil, right by the apartment "Walter Buchmann" bakery has exquisite (vegan) doughnuts that we had a hard time resisting.
Communication and check-in were easy. The apartment is quite small and on the very top floor, as is clear in the photos. I'm tall but didn't find the peaked ceilings a problem as it can be in apartments like this. The amenities were basic but we had everything we needed for our stay. We were only here for 3 nights and did not cook at home, if it was a longer stay I think we would have felt limited in the kitchen.
Good for 1 or 2 people having a short stay in Zurich who would appreciate this location.
