We didn't get to meet Domenico, everything was done remotely and it was super simple and clear. The apartment is exactly as pictured but you can't appreciate from the pictures how clean it is (really clean!). There is a small washer and dryer that work well.
The apartment is in the main tourist area and central to everything a tourist wants to see. That means a lot of tourists and noise...but the apartment windows are incredibly good at keeping out noise. You will have no problem with noise with the windows closed and the air conditioners on if it is hot (it was > 30C during our stay.
The apartment is on the 2nd floor, 39 steps up. It was a good workout with luggage in the heat. Unless you have serious problems with stairs this is no problem but take your time with heavy luggage (the stairs can be slippery).
Domenico left a very helpful list of nearby stores and restaurants. Our daughter has Celiac - there is a *fantastic* gluten free restaurant nearby family restaurant called Ciro and Sons. Add it to the list and go there, so good even for non-gluten free.
Highly recommend this apartment!!!
