My friend and I stayed at Sarah and Thomas’ lovely flat for 3 nights in August, and I highly recommend it as a place to stay in Vienna!
The apartment block was easy to find using public transport from the airport, plus google maps, and the check-in process was very simple and efficient.
The apartment is beautiful, light, airy and spacious. There was more than enough space for two of us (my friend slept in the bedroom and I slept on the very comfortable sofa bed) and we were very happy we went with this place over a hotel! There is a U-bahn station nearby which is very convenient, and a tram stop 5 mins walk away from which you can go straight into the centre of the city.
Sarah and Thomas are very fast and friendly communicators, and made us feel welcome! :)
