Very clean and stylish apartment located in a very quiet part of the center.
It was 10-30 min walk to almost any attraction in the city we wanted to visit. We bought metro trips, but haven't even used them to the full as all was located conveniently close and we preferred to walk. We were with a 1-year-old baby and hosts offered us to provide a baby crib which was great and helped a lot.
The only thing that might be a disturbance for someone is that you can hear the transportation outside the apartment as the windows are original old building windows, but the noise level is not higher than you would expect staying in any other old building.
We would definitely stay there again.
