As mine and my girlfriend's first Airbnb experience, nothing could have been better (except for we got lost in Vienna).

Communication with Jan was without problems, with fast responses and helpful information. When we asked for an advice, Jan seemed to have no problems answering us.
Thus, to stay at his place was not only about the act of booking and paying, but also about nice talk we had.

To make long story short, Jan's place was nice, cosy and even though we stayed in office, it felt quite homely.
Distance to city centre was as made for night walks, when you do not want to walk a lot.

Try him, you will not regret his friendly attitude.
