Christoph was an absolutely wonderful host. He was communicative early on, emailing me frequently about the accomodations, arranging logistics, etc.. When we arrived, he was there to meet us, show us around the apartment and even took the time to show us some of the major sites on maps. He recommended some great places to eat and over all was very courteous. The apartment was very comfortable. We stayed in Vienna for a week and this place really felt like home. Christoph was a kind and gracious host and after the end of our stay I feel safe to say that I now have a good friend in Vienna.
