We booked the location Lindenstrasse but was supplied an apartment on Kieselgasse, just a short walk away. The team at City Stay communicated about this so there were no problems.
The apartment was very nice in a great location, it suited my family and I very well for our trip to Zurich. The location was very convenient - close to the tram, the lake and many restaurants.
The checkin and checkout process was very simple.
