Although I was not often at the apartment, Gabi was always available to help and have a chat. They were very friendly also.
You have a large room (with a chandelier!), shared bathroom and kitchen (including coffee machine), and overall plenty of space.
The view of the Danube is fab, and the location is overall very accessible, with lots around. I didn't use any public transportation for 2/3 days, and when I did it was very easy to go from Schwedenplatz.
