We stayed in Alberto's apartment while hunting for our own as we moved to Zürich from the UK. It was wonderfully located, a few minutes from the main train station and perfect for skipping around the town sorting out the various administration we needed to get done.
Only criticism was that the bedroom did tend to get stuffy, due to the lack of airflow through it. However, we were visiting during an unusually hot summer!
Otherwise, it had everything needed and was a great start to our life in Zürich.
