Beautiful house with high cieling, wooden floors and comfortable furniture. More spacious than we expected. A lot of kitchen equipment. The location was perfect for our purpose, very close to the conference venue. It is also not far from the city center, and there is a closeby tram station.
Good and fast communication, we run into an issue with the toilet, and the next morning it was solved.
Overall, a great Vienna experience. I would stay there again, and suggest it to anyone with eyes closed.
