Sofia's place is beautifully furnished, everything is new and stylish. There is a tram line in front of the building, which drives you directly to the city center (and, of course, make interconnections with metro lines), so everything is easily reachable. In the street, you have markets and nice fast food restaurants.
Sofia was responsive and caring, about any questions we had. If we come back to Vienna, we would come back to this place too :)
