Great service: we got a free upgrade for a much bigger apartment. The place was very clean and had all appliances one would expect for an apartment. Full option kitchen, 3 TV's, even a dry sauna (unfortunately, we did not have enough time to use it).
Great location: 5 minutes to the U-bahn with direct connection to Vienna, 2 minutes to a SPAR grocery store. There are several restaurants in the area and the stadium seems very close.
