Werner and Mariola have a lovely, spacious modern house in a quiet suburb of Vienna near the terminus of the U1 subway line. I felt very welcome and comfortable during my stay, and was encouraged to use all the facilities of the house, including a bicycle. Both hosts were at home, and another family was staying as well, so there was always someone to chat with. The location would not be suitable for anyone who wants to be in the city centre, but for me it was no problem at all, as the house is only a few minutes' walk from the U-Bahn station and less than 30 minutes from Stephansplatz. There is even a direct train (S7) from the airport, taking under an hour and costing only 4.3 Eu. I would definitely like to stay here again.
