We had a wonderful time in Zurich and Hyesook was great. She was flexible with our check-in and met is right at the door. We had a great conversation with her about the neighborhood and where to go to eat and see some of the nearby highlights.
The flat itself was very cozy and accommodating. The noise of the neighborhood was definitely there, but not enough to be a disturbance.
Access to the main Zurich train station is VERY convenient, and the old town is all around you. We were all very happy with our stay and would recommend Hyesook to anyone looking for a nice place to stay in Zurich.
