Flo is a hospitable host. Although he was not at the time when we were in Vienna (he warned about this in advance), his roommate showed us the apartment and all the amenities and was hospitable and welcoming. Students live in this apartment, don't forget about it. But we were ready for this after reading the reviews. In general, the apartment and the room are excellent! There are all the amenities. The guys did not bother us absolutely. Also this apartment in an old house near the city center. The apartment is huge and impressive in its size. Therefore, I put 5 stars definitely.
