I'd highly recommend staying here if you ever make a trip to Vienna. The apt was very central (5 minute walk) to the central plaza and museum quarters conveniently located in the Japanese neighborhood. The host had sent out multiple messages prior and during my trip with directions and recommendations for the city. Communications was exceptional - I was hours late for check-in than expected due to a flight delay, but Dorian was patiently waiting and made sure I had all the info I needed upon arriving.
The space was spotless and well decorated. They even put out a welcome framed photos of me out (off of Airbnb which I thought was extremely cute) I felt very comfortable staying there, and it was so easy coming back for a quick rest from walking around all day given how central it was. 10/10 would stay at again if I ever make a trip back to Vienna!
