The apartment of Yannick is the best option if you are planning visit Wien. It's nice, tidy and clean, really well located, literally in front of the metro station, so you could reach the center in 10 min.
Yannick is a very nice guy, he helped us in everything that we need. Even when we want to see the game between Chile and Argentina (Chile won and is the champion of the Copa America) he let us use his laptop to see the game!! and when we had the opportunity to talk he was a very very nice guy! thank you very much for everything!! we really enjoy our stay in your home!
