My friend and I stayed three nights in this apartment. The reviews say it all: it's clean, convenient to best parts of the city, quiet and very comfortable.
The main advantage of this apartment over many I have stayed in, is the service provided by Thomas. He was impeccable from beginning to end. I have stayed in many airbnb homes over the years, the service Thomas provided us was above and beyond all others. If you want smooth and attentive entry and exit, great tips for the city and a kind human being to have access to in Vienna, you would want to stay at this apartment. Thank you Thomas!
