We stayed there for five days, a family of six and we were very comfortable with one room and queen beds around the living room. The location is outstanding. Vienna is a big city and the apartment is in a nice neighborhood, in the center. It is not in a tourist area, so it's calm during the night, but as I mentioned you are completely in Vienna's city center. The house is very clean and comfortable. It's lighting and spacious. They received us perfectly on time, they explained us everything we need and they supply us all kind of information from tourism in a notebook with maps. I will be happy to stay there again my next time in Vienna
