Having lived in Vienna for 18 years, I know the city and in particular the 3rd district where this flat is located. It’s really a nice deal and the charm of a Fin-de-Siècle house always brings up nice memories. The flat itself was properly equipped, key handover and dropping went smoothly, truly recommendable. Btw, be prepared there is no elevator and the flat is on the 3rd (Viennese 2nd floor). No big deal for me, just for the record.
