We travel since 2015 with Airbnb and Kerstin flat is really amazing ! Really one of our best experience. The location is perfect, in front of HKM and Museums Quarter but also near Hofburg and you have also supermarket 50 m from the flat. The apartment is perfectly clean, very nice, well equiped, luminous and also very quiet ! Beds are comfortable and the leaving room very pleasant. The 2 bedrooms are perfectly separated. Communnication with Kerstin was really easy and we obtained quick answers. We loved our stay there and I hope to have the oppotunnity to come back. Highly recommanded !
