Helene and her husband are perfect hosts. Since the reservation, she answered my questions very quickly, with lots of information. When we arrived in Vienna, they were waiting for us in the apartment and they explained about everything we could need in the apartment and in the neighbourhood. The apartment itself is excellent, very well equiped, with everything you might need. It is also big, very clean and extremely organized. They also offered us a bottle of Prosecco for the night and cereal for the breakfast. We enjoyed very much our stay and we truly recommend.
