Norbert was very welcoming and accommodating. He gave us a map of Vienna with information on the public transportation system, which was really helpful as Google Maps had limited public transit information. Norbert was mostly responsive via Airbnb messaging. The apartment itself is very spacious and clean. We had pretty much no concerns or problems. The apartment isn't necessarily close to the main central area of Vienna, but it's very public transportation friendly. I would definitely recommend this location for those touring around Vienna for a couple of days.

One last note: For the key deposit, you basically pay a 50 euro deposit up front (not included in the Airbnb charge) and sign a paper. At the end of the stay, the 50 euros will be returned to you.
