The location gave easy access to trams and buses which led to all the sights we wanted to see, and the space itself was comfortably spacious for our 4 adults and 2 children group.
All the basic amenities were available as described, but additional maintenance would be appreciated as the roller shutter for the balcony door was broken, and the swinging window shutter for one of the bedrooms doesn't close properly (which is kind of a bigger deal because it's a ground floor unit and the bedroom window faces the road). People who are sensitive to noise might want to take note that 2 of the 3 beds are excessively squeaky, and on one morning (but only 1 morning out of 3) we could clearly hear footsteps and shuffling from the unit upstairs.
But if you're looking for a home base to explore Zurich in a larger group, it works just fine!
