Can only recommend this variant for your visit to Vienna.
Anita and Alex were very helpful and friendly. Everything in the flat worked well. Location is great: by the river, close to the Rossauer Lände UBahn station, Augarten park and 24hour opened cafe Prindl. Not far from the flat you can find stores like Billa and Penny Markt. Donau's embankment and Augarten park are great for walking/running.
