It was really great! Susanne is very friendly and sunny host. She has so cozy flat with amazing library. I felt as at home.
We rented flat in December, and it was so warm inside. Beside this we had a lot of pans, beautifull cups's collection with elephants and super soft blanket. And at night a saw photobook about Merilyn Monroe instead Instagram :-).
Highly recommend this flat if you are going to Viena.
