Alice was at all times very fast in answering my questions and messages. This was already the case before I had confirmed my booking at airbnb, and it continued throughout the periods before, during and even after the actual stay. I didn't get to meet her in person, but during a telephone call we had on the day of my arrival, she was very helpful and clear on explaining how certain things worked.
Her apartment is conveniently located in the 12th district (Meidling) between the U4 Margaretengürtel and U4/U6 Langefeldgasse stops (which can be each reached within 5 minutes walk). The tram lines 6 and 18, as well as bus line 12A, have also stops nearby. Immediately in the next building there is a Hofer supermarket located, and nearby the Langefeld metro station there is a Billa and a DM drugstore. There are some nice eating venues in the direct neighborhood, both for take out and sitting down. I particularly enjoyed 'Turkis' at the Langefeld U4/6 stop with their very friendly staff, and the 'Gastätte zum Fabrik' (next to the Hotel Fabrik) where they serve excellent Austrian food at reasonable prices.
The apartment itself is on the second floor, which can be accessed by private key elevator, and is very quiet as it located towards the inner side of the building. It is very bright and with much light because of the big windows that are in every one of the rooms.
