We slept only one night at Stefan’s place but that was enough to experience outstanding hospitality by Stefan. He is great and very friendly host who helped us a lot and also gave us precise instructions about the place.
Place itself is really great in oldish Vienna building, stylish, clean and on very nice location. It is very close to the city centre and during the night is perfectly quiet because it does not overlook street but a small park between buildings. Highly reccomended!
