A beautiful apartment in the heart of the city with a killer view of the square. Amenities were really appreciated, as well as the guides to the city. A/C worked nicely when I needed it, otherwise the windows provided just enough cool air. The noise of the square was never really a problem, even when the bachelor/bachelorette parties rolled through later at night. The hosts replied promptly to any questions, and really added nice touches to the place. I'm definitely looking this apartment up again if I return to Vienna.
