Heni & Walter were outstanding hosts. They took care of every small thing right from start to finish. The communication was outstanding before and during the stay. The apartment was very close to the main station as well as the underground which made journeys possible without hassle. Also a lot of supermarkets and restaurants at short distance by walk or by metro. Small gestures like leaving a rice cooker behind were very much appreciated. We also talked of Vienna being very hot and next day we were surprised with a pedestal fan in the apartment - something we felt very touching. Will recommend them any day for a short stay.
