Judith's place is an oasis of calm and comfort, in a quiet neighborhood but at the same time very centrally located. You can get to anywhere in Zürich in no time thanks to multiple public transportation options in a 10 minutes walk radius, and you can also rend bikes to ride anywhere at several publibike stations close by. There is a great bakery 5 minutes walking distance down the street, Coop and Migros for grocery shopping, and many restaurants close by too. Of course, you can use Uber Eats to have great food delivered from the very diverse food scene in Zürich.
We stayed in the apartment with our two girls of 2 and 5 and it was perfect. There was a lot of room for them to play, tons of toys, board games, and books to keep them entertained, and when we needed to get some air we headed down to the cozy backyard with a little swing set. Our kids actually had more fun looking at the three beautiful chickens who stay in their coop (but are super quiet, we never heard them from inside!) and roam around the backyard every evening when Judith takes them out.
The apartment also has everything you might want to cook and entertain, complete with a fondue and raclette sets for these traditional Swiss meals :). Beds were very comfortable, and you'll get a ton of light in all rooms thanks to all the windows (wich all have shutters so you can make the rooms nice and dark for naps).
Two things to be aware of, that do not make Judith place any worse but that might be important to you: first, parking on the street is almost impossible so if you plan on having a car be aware that you'll need to rent a spot from Judith, which we paid CHF 15.-/day. Second, there is no washing machine in the apartment for doing your laundry. Judith provided us with mesh bags that we gave her filled with laundry whenever we needed, and she always had it done in a matter of hours. We then put the laundry on drying racks in the apartment until it was dry.
Overall, we had a wonderful time at Judith's and would recommend her place to anyone looking for a place to stay in Zürich. We stayed for a month when we were moving back from the US to Switzerland, and it was great to know we had everything we needed. Judith and her family are very friendly, speak fluently English, French, and of course German, and will do everything to make your stay the most comfortable!
