Churyon and Stephan are wonderful hosts. The location is easy to find and the check-in was smooth. It's a really nice and well equipped flat, with great bathroom and kitchen. We came during the hot Summer but our room was still comfortable, especially with the fan provided. The stations and supermarket nearby also made things super convenient!
Most importantly, they are really nice and helpful people, willing to give you travel advice etc. And it's great chatting with them on the balcony, whether the topic is about Zurich or just anything else :D
