Christoph is a wonderful and very helpful host! He was flexible about the check-out time and that saved us almost half of a day for sightseeing (Thank you once again Christoph!). Christoph can give you an advice on what places to see and how to get there. The apartment is fully packed with all the things one might possibly need (even a medical chest in case you get sick). The apartment itself is quiet, clean and a furnished with great taste and attention to details. The apartment is located close to the most popular metro lines U1 and U3 (10 to 15 minutes and you are in the heart of Vienna) and the S-Bahn (that takes you to the airport). There is a huge and wonderful Prater amusement park nearby, as well as several supermarkets and restaurants. I will definitely recommend this apartment.
