Wonderful apartment, we had a lovely stay! Hyesook was very welcoming, met us in person (eacy check-in process), and there is a comfortable place to leave luggage before check-in and after check-out which was very convenient for us. The location is excellent (very close to the main station, but not noisy), the place is quite large & the beds in particular are fabulous (huge & very very comfortable) & the kitchen (and rest of the place) has all of the amenities you need. The only tiny caveat is that it is 4th floor, but this is mentioned clearly in the site, and is definitely compensated for by everything else - so with Hyesook's place you get a lot more things for the price you'd pay for other places, just take this into account if someone in the party has trouble with stairs. We would definitely book this place next time we are in Zurich.
