Excellent apartment. Very clean and spacious. Great location for exploring Vienna, just 10 minutes from the centre by metro or tram. Fans were now installed in every room that helped considerably with the heat we experienced during our stay. The only problem we found was that it was too light in the mornings as the semi-transparent curtains didnt prevent the light entering the apartment. However, surprisingly I didnt see this mentioned on any other reviews so it could specific to us. Check-in and communication was quick and easy.
