I stayed here with my mother and sister for 4 nights. The appartment was very clean, well equipped with everything needed for our staying. Wolfgang is a very nice owner, he helped us with local tips and came to greet us when we arrived.
The neighborhood is peaceful and around the place there are grocery shops and some nice pastry shops.
It is 5-7 minutes walk from the metro station and from there Schönbrun is about 30 minutes away and Hoffburg 20 min.
I would definitely recommend it!
