We spent our Easter holidays with our two kids (3 and 5 years old) at Judith's apartment. The apartment is very spacious and clean - as announced - and very comfortable for a family stay. The kitchen is well-equipped, so cooking at home is definitely possible. There are even toys available (with the negative effect that it was a challenge to get our kids out of the house ;-)).
The location of the apartment is ideal: it is in a quiet neighborhood, but at the same time it is only a 5-minutes walk away from the train station Binz, which means that the Zurich main station (Zürich HB) can be reached within two stops (about 10 minutes). Furthermore, neighborhoods such as Wiedikon or Enge are within walking distance, and Uetliberg is only 15 minutes by train. There are also restaurants and supermarkets nearby.
Last but not least, Judith has been a great host. Communication with her has been very smooth, and it was obvious that she wanted us to be comfortable in her apartment. For example, she gave us a hand with the laundry, and she checked regularly on us to make sure that we have everything we need.
In summary, I can definitely recommend this apartment. We will try to stay there again the next time we visit Zurich.
