Probably one of the best Airbnb experiences I've had, Laurence met me in the morning and made sure we had everything we needed including excellent personal recommendations of where to eat and a huge selection of guides for the various attractions.
The apartment is beautiful (even more so that the pictures show) and impeccably clean. An 8 minute walk from the central station and two stops from the city centre means getting around is very easy.
Communication was very quick and easy and the whole experience was a delight. If you're staying in Vienna this is an excellent choice!
