Astrid was not in Vienna while I was staying at the apartment so I did not meet her but communication was always timely, friendly and clear. Check-in is straightforward and the apartment is practical and functional. The location is an excellent base for a visit to Vienna. It is conveniently located to get in to the centre in just a few minutes on foot or by public transport and there are many good restaurants and shops very close by. If you expect to spend much time in the apartment, just be aware that it is on the ground floor looking into a small courtyard and therefore does not get a lot of natural light. I would not hesitate to go back.
