Lovely apartment, very clean with three good sized bedrooms and a nice spacious living area. Communication with the host was excellent with any queries being responded to promptly. We also arranged transfers to and from the airport with Adam. The location is a bit out of the way but it's only a short walk from the metro so we didn't find this a problem. The only slight negative was that in two of the bedrooms you can hear quite a bit of noise from the road which may be a problem for light sleepers, especially if it is hot and you have to have the windows open like we did. Overall however we really enjoyed our stay and would definitely recommend this apartment and Vienna itself!
