We spent three days in Vienna, in Belinda's apartment. We haven't met her but she's been very punctual in the communication, kind and accomodating with the check-in time. The apartment was clean, elegant and there's all you need to rest and relax. The bathroom is quite small but useful; there are the wi-fi line, the tv and instruments for cooking.
The apartment is not very close to the center of the city, but with 25 min on foot or with public transports (there's the tram n.1) you can easily reach the Innere Stadt. It's also 1, 3 km far from the Hauptbanhof station, where you can take the train to the airport. Very recommended!
