Nice small flat (2 bedrooms + 1 living room and small kitchen and bathroom) in quiet area of Zurich, 10min. walking distance from major train station. Organization and check in from Jung Soo was perfect and very fast. Unfortunately, we did not meet Jung Soo, as she was away and later staying with friends. Flat OK for 1-2 guests, seems to be quite small for more guests (we are a family of four), as then guests have to sleep behind shielding screen in living room.
If you don't like muesli, you need to bring along your own breakfast (our kids unfortunately went on strike).
