The place is located in the middle of the city center. The appartment looks like te pictures, and is rather spacious. However the ceiling is pretty low, so you will have to mind your head. Price/Quality wise, this is probably one of the best options within the expensive town of Zurich.
The host is really helpful (in multiple languages) and responds promptly. He also works in a hotel, which can be seen by the way the appartment is taken care of.
When going to Zurich, I would definitely recommend this place.
