It's our second time here, but at a different, bigger apartment, also managed by Markus.
Markus as always is very accessible and helpful, can be reached by phone and responds to messages very quickly. We had a little difficulty with our check-in timing, and he was very helpful.
The apartment is very user friendly, cozy, furnished original vintage, a quintessential Viennese residence literally within 10 minutes walking distance from all the landmarks of the city.
Highly recommended!
