Great place! We were forewarned about the stairs and it is rough if you are bringing a lot of luggage but it's only 3 flights (a bit narrow). The apartment is very cute and very clean! We had everything we needed and the bed was comfortable. The shower is small and the glass for the tub only comes half way so be mindful! Tina was very responsive!
The Airbnb was only about a 10-15 min Uber ride to everything (rathus, ringstrasse etc). The furthest place was schonbrunn palace at 20 min with traffic. The airport is also 20 min away without traffic.
Highly recommend :)
