We had a great time in Vienna during three days in Max's appartment. The appartment was very clean and well decorated. Even if we didn't meet Max we had a really good contact with him and he arranged everything for us during our stay.
It is not far from the center and in a nice neighborhood, next to naschmarkt wich is really nice and on the way to Schonbrunn castle.
We definitely recommand this place to stay in Vienna!
