We are s amall family (parents with a teenager girl) stayed for a week in October/2022 in that apartment.
Dominik and Kathrin are wonderful hosts, the communication with them was always fast, and we've got all the answers to
our questions. They were also very kind and allowed us a two-hours later check-out.
The apartment is as described in the AirBNB site (pictures and descriptions).
Location is central, just 4 stations by U1 from Stephanplatz.
It's is a very quiet area, still there are few supermakets and restaurants nearby.
Hope to return to that apartment in my future trips to Vienna.
