My stay in this apartment was absolutely perfect. The building itself is very beautiful, with high ceilings and cute patio. The apartment is very bright, modern, clean, has everything one needs (and even more). Lisa is a wonderful, remarkable host, she was ready to answer all my questions, gave me a lot of tips for visiting the city plus there were lots of different maps and helpful notes in the flat. The location is great, central but quiet. The way from/to the airport is really easy from Westbahnhof by bus.
I highly recommend this apartment and will definitely book it again.
