My girlfriend and I were greeted by Alexander's mother. The apartment was clean, comfortable, and very conveniently located in a quiet district close to the historical center.

It only takes a few minutes to walk to "Sudtiroler Platz - Hauptbahnhof" U-Bahn station, which is three stations apart from "Stephansplatz" on line U1, hence it only took us 10-15min everyday to get to the center of Vienna.

Our favorite museum in Vienna was actually the Belvedere schloss (the Klimt paintings are stunning!) which is within walking distance (15min) to the apt, so this was a plus!

Listing is accurate, internet via wifi was fast, no air conditioning but pulling down the blind and opening the windows was sufficient to have the apartment stay cool (even when it was > 30 C outside). There are also restaurants and grocery stores in the neighborhood.

One detail: the apartment can host three guests because a large air mattress was added next to the bed. We had no problem sleeping in it, as long as it is well inflated.
