We had a great stay at Silvia’s appartment. It is very cozy and nice. Plus it is very a good location. You can go walking to Schönbrunn, and there are many buses, trams and metros tha can get you to the center easily and quickly. I would defenitely stay there again if I had to go to Vienna. The host and her parents were very nice. The only thing I would improve is to put a door in between the main bedroom and the kitchen, so one can sleep while others are cooking or whatever.
