Christoph was very thorough and prompt throughout the arrival process. His directions were clear and I felt comfortable finding his flat off the public transit. When I arrived Christoph was very respectful and welcoming and made me feel very safe and at home immediately. He is a gracious host with a beautiful, clean apartment. The bedroom is as spacious as the pictures show and the bathroom was very clean and worked well. Christoph was more than willing to help me with all my personal needs and was very patient suggesting places I might like to visit and how to get there. His flat is an easy walk to the metro which is only 1 stop from the train to the airport and 2 stops to the city centre. The neighbourhood is pretty and safe. I had a lovely time staying at Christoph's and highly recommend his accommodation in Vienna.
