Location, location, location. The flat is just in the middle of the action. There are plenty of restaurants and bars on same street , even one below. Do not worry at the noise. My family did not hear anything. Cleanliness and communication with Luigi was fast and easy. They were waiting for us when we arrived. If your party is of adults, event better, you are on the center of action. We used it as a hub and did the typical tourist stuff. Walked 75% of time from the flat and used Uber only when we were tired. Remember you are visiting a very old city, therefore all buildings are part of history with its aches. Internet was fast.
Wish all the best to Luigi and family
