The apartment is perfect for couples, even a smaller group of 4 people. A 3 minute walk from Westbanhof, Mariahilfer and Stadthalle. We went to a concert at Stadthalle, and I cannot tell you how happy I was that we could skip the crowded subway rides, literally just walked there 30 minutes before it started.
The host is ready at your disposal 24/7 for whatever problem you may have, and I have to give extra stars for that :-) Just one minor flaw: there are no doors on the bathroom it is separated by a shower curtain only from the rest of the apartment. Nothing to worry about if you are travelling with close friends or alone. Other than that, everything was immaculate. The apartment is cosy and very quiet. Thank you for a lovely stay Peter!
Also, try the restaurant just right on the corner, Pulkautaler Bierhaus, nothing better than a home brew after a long day of sightseeing.
