Stefan is a very responsive and thoughtful host. The place was squeaky clean when I arrived and it has all the amenities one needs, and more. It is also outstandingly, if not almost eerily, quiet. While not bang central, it is very well close to many bus, tram and an U-Bahn lines, and the public transport system in Vienna is truly outstanding. There is also a supermarket round the corner and plenty of shops, restaurants and cafés in the vicinity. All in all, I had a wonderful time in Vienna.
