Fantastic place and a fantastic host - Illia! The apartment is new and super clean. The host was really helpfull and knows how to communicate with the guests.
The apartment is further from the city center, but I do recommend to stay here as the most popular objects of Vienna are located closer to the apartment. If you are not a hiker like me mind that it is really easy to get to the city center with a trolley, a bus or event subway (metro).
5-stars!
