We spent 4 nights in Theresia's lovely room and we were very impressed. The room is exactly as pictured and equipped with everything you'll possibly need. We didn't meet Theresia, but she gave very detailed instructions and Rupert came to check on us and made sure we had everything we needed. The house isn't in the city centre, but it's very well connected to public transport and close to lots of shops. If you're coming to Vienna, we definitely recommend this place. My boyfriend Gareth went as far to say it was "the best Airbnb I've ever stayed in" :)
