I enjoyed a great stay in Vienna, and staying with Christian was very easy. His communication prior to my arrival was excellent, he met me upon arrival, explained everything I'd need to know, provided a local map with directions, and respected my privacy. The place is very close to all amenities (supermarkets, metro, ATMs, and restaurants etc), and isn't far from the downtown areas via metro. The apartment is very clean, stylish, and comfortable with everything available for you to use including kitchen and laundry. A great stay and would certainly recommend to others.
