Mario is a great host. He got in contact regularly to make sure everything was OK in the apartment through my 6 week stay. The apartment is quiet, on the back of the block away from the street. It is warm and comfortable through the winter months. Very well located for Oerlikon and connections to anywhere through the train or tram system. There are many local stores for food purchases, including in the station. Easy, convenient check-in arranged at a good time for both of us. Simple check-out.
