Christian is a superb host. He answered very quickly all my E-mails, gave me a very warm welcome, good advice as to where to go (1/5 events in Vienna...) and generally, gave me the feeling that I'm in some kind of a far family visit. The directions on how to get where, were very clear and helpful. Christian took care to all my needs. I think the way Christian did his part was a great example to the airbnb spirit and I recommend everybody to enjoy its pleasantness!
