I highly recommend staying at Christophs place, its located very close to the Schönbrunner Schloss and also the room itself is nicely decorated to make you feel at home easily. He has some very good advices for you and tries to make your stay as pleasant as possible. We enjoyed our stay in Vienna a lot and are very glad to have met two lovely new people, take care Christoph and Alina, hope to see you again one day! ;)
