The flat was exactly as described. Yes, it's on a busy road, but the double glazing is good enough to cut out the noise so that we were able to sleep. (And we're very sensitive to noise.) The location is great, very convenient for everywhere in town and moments from the U-Bahn station. Vienna's public transport system is superb, so it was really easy to get to the sights from the flat, even though one of us had limited walking capacity. We didn't actually meet Steven, as he was busy elsewhere, but his cleaning lady showed us in and she was very polite and helpful. Steven was always available on e-mail and he was able to answer any queries that we had about the area very quickly. Incidentally, the WiFi is really good.
