Christoph understands what it means to be a good "host" and he takes pride in being a good host! His room is quite splendid: large, very clean, bright and very quiet. There were some nice personal welcoming touches when we arrived. The location is also very good; you are 5 minutes from the metro system, and you can also walk everywhere, which we did. Christoph gave us good advice; he has a lot of tourist info available in the room and he arranged for us to have supper in different typical restaurants each night, which we really enjoyed. Vienna is a splendid city and Christoph complements the joy of the visit in every way. Highly recommend.
