Rossana's place was perfect for my stay in Zurich. Though it's outside of the city center, it is a quick walk to the public transportation and there are also lots of restaurants and a supermarket within short walking distance, too.
I had everything I needed, and the check-in/check-out process was simple. I definitely recommend staying here if you don't mind staying outside of the city center. I actually walked all the way from the Lake Zurich area back to the apartment instead of taking public transportation, and it only took me about 30 minutes. (Just an FYI if you like to walk.)
