I did not get to meet Sylvie as she was away during my stay. however, the cats were great host. communication was great. If you like prefabricated Airbnb's this is not for you. Sylvie is gracious enough to share her flat and it is quirky, homey, and great for adventures around vienna. you are a bit outside of city center, but that did not pose any problems. Great if you want authentic Vienna stay
