We've spent 4 nights at Concetta's apartment in October. The location was great! It's inside the city centre, historical quarter. The train station, metro, walking streets and many of the attractions were nearby.
The flat was fully private and clean with the most important equipments.
It was quiet during the nights. A little bit of traffic nosie could be heard during the day, but it's the cost of such great location! (Also hopefully you will spend the day time with exploring the city and its area, and not in the room, hehe)
Both Concetta and her son were really kind and welcoming. The check-in was smooth and fast.
I'd definitely recommend this flat!
