the appartment is great, with 4 independent rooms and a private terrasse. It was very clean and well furnished. The indications from Christian were precise and, even if we did not meet him, he was reactive to answer to every questions we had. The appartment is directly connected to the historic district of Vienna with Tram 62 that is just down the flat. If I have the opportunity to come back to Vienna, I will try to be hosted in this flat.
