Dieter's apartment was even better than we expected. It has stunning old architectural features, but is updated where it counts. The view over the Danube is amazing and a wonderful sight to wake up to. We had a very comfortable stay and were provided with coffee, soaps, and Viennese cookies, among other things. The apartment is just across the water to the metro, but it's also a beautiful walk along the water into the city center. I would highly recommend staying here and hope to stay again myself!
