We had a great time in Vienna and this was in no small part due to Christian's flat, and all the great information he gave us. Christian met us on our arrival and showed us around the flat, and told us where we could find everything, and he also provided us with great information about the neighbourhood and the city. The flat was excellent and immaculate! It was very modern and stylish and had everything that we could want, and more. It's located just 2 minutes from an underground train station, and is around a 25 minutes leisurely walk from the city center. We can certainly recommend Christian's flat.
