Everthing checks out! The apartment was convenient and super clean. I don't recall any issue at all with the stay. It's far enough from the crowd of a big city but close enough to get to the spots with a short walk to public transport. Spacious and full of artworks.
Besides meeting such a fantastic host and having an extraordinary place to stay when travelling in Vienna, we also had very interesting and profound conversations with Alexandra. I'd like to assure future visitors that Alexandra's place itself should be one of the must-see spots of Wien. Five stars, no hesitation.
