I enjoyed my stay! The hosts were friendly and helpful and they made me feel relaxed and at home! They also provided useful info on how to get to the apartment (there is a regular bus from Oerlikon train station, though you can walk if you like as it is a short distance). There are regular & fast trains connecting Oerlikon to Zurich main station. Or you can take a nice walk through the woods to the ETH Hönggerberg campus.
