We were a family of 5 and really enjoyed staying in this apt. The apt is in a great location walking distance to most things. We took daily walks about 1-2 miles to old Zurich, the beach, train station and to other touristic locations. It's clean modern and nicely furnished making it very easy to feel at home. There's also a grocery store walking distance from the apt so we were able to eat in especially for breakfast.
There's two beds the master is upstairs and I would say the only downfall to the apt is is it gets hot at night- you can open the windows but not much air flows. The first floor has a/c which we definitely used daily. It's also a little noisy early morning bc there's construction outside but I'm sure that will soon pass when those apts are completed. My older two girls slept in the bed downstairs not sure how comfortable it was but it's a little tight for adults great for kids. The owner provides Netflix so if you do stay in you can binge watch shows which was also a plus. Overall I would stay here again!
