Our stay at Andrei's flat was great! The place is small and cozy and stylish as well. Very clean with all the amenities you need for a couple of days in Vienna. Location was great as well. Right off one of the busiest shopping streets in Vienna and a 25 minute walk to the inner city, christmas markets and parliament. There are metro stations minute away that will take you anywhere within the center in minutes, if you don't wanna walk. Florian who was taking care of us was also very helpful and always quick to reply to our questions. Would highly recommend staying at Andrei's flat.
