I stayed for only one night, for a concert at nearby Hallenstadion (a quick journey by bus followed by a 5 minute walk). The place is convenient to both the stadium and the airport, and it was no trouble to get into the centre of town for an afternoon of walking around. Vincenzo was the perfect host -- he let me drop my bags off when I arrived early, he gave great directions for getting to the flat via public transit, and he had fantastic tips for what to do with my limited time in Zurich. (In my case, I went to Uetliberg and enjoyed walking in the sun!) It was a quick stay, and I had everything I needed for it.
