I had a lovely time at Assefash's home as a (solo traveling) woman in Vienna! The building of Assefash's home is as gorgeous as the rest of Vienna. It has an elevator and is located perfectly, with supermarkets, cafes, shops of all kind and all the major sightseeing spots in walking distance. The surrounding streets are actually very busy but the apartment seemed like a quiet oasis, just off one of the more busy streets. Alternatively its also very close to metro and bus stations that will take you wherever you wanna go. Assefash herself was very accommodating and understanding (I had missed a flight and arrived a day later than expected, also concerning check-out times) but also a lovely conversation partner :-)
