We loved our stay in the apartment of Jan and Sarah. From the guides and emails of Sarah, the warm welcome of Jan to the nice communication even after we were home, everything was great! We would definitely recommend this apartment: location is very central, but the neighborhood is quiet. There is a lovely bar close by which will definitely check out next time. We used a recommendation in the guide written by Sarah and Jan and it was really good. We unfortunately only could stay for two nights due to our schedule. We hope to be back soon and to be able to enjoy both Vienna and the apartment again!
