The apartment is 4 minutes by walk by Prater train and metro station and well connected to the airport with train S7. We didn't meet with Josef but communication was perfect (fast and detailed) and check in too. The building is old and don't look so nice; however the apartment is nice as described in the pics. There a large dining room with table, sofa and tv and a large bedroom. Coffee and tee are available and the kitchen is served with all the stuffs. Everything was clean. On the street there is a delicious Turkish bakery, every morning we had the sweet breakfast there. Prater is 10 minutes by walk. Center 8 minutes with metro or 25 by walk. Recommended place to stay in Wien.
