Denys' apartment is precisely as described.....modern, super-tidy, perfectly located. It was just right for our 4 nights there.
The location made it easier, with access to all public transportation within walking distance.
The check-in instructions received were absolutely accurate, making it easy for us to access the apartment even though we reached late at night.
Denys was a wonderful host, quick with responses and recommendations, whenever required.
Would definitely recommend a stay at Denys' whenever in Vienna.
