I stayed at this flat for two nights on a very short trip to Vienna. Though I was out most of the day, the flat was in a perfect location for me as I was doing many of the tourist activities in the centre of Vienna. Lilly was a wonderful host, quick to respond and no issue with check-in or check-out. The flat itself was clean, comfy, and if you're looking for a centrally located place in Vienna this is the place for you.
