Very nice apartment with a perfect location for exploring Vienna! Public transport is right downstairs and many of the most important tourist sites are only a 10-15 min walk away. Apartment was clean and Albert met us upon arrival and gave us some recommendations for Vienna.
If you happen to be vegan this is a perfect location. There are 2 vegan restaurants on the block, vegan gelato right downstairs, and several other options within a 5-10 minute walks.
It is not the quietest location during tourist season with many people out and about on the plaza through much of the night, but this is the only downside. For us the noise was worth the convenient location.
Highly recommended!
