We enjoyed our stay at Filippo's apartment. Great flat exactly as shown in the photos, it was very clean, had all necessary amenities, was very comfortable, including the sofa bed. It is in a great location for seeing the sights.
Only drawback for our long stay (3 weeks) was only being offered one set of keys and the door buzzer not working. As others have mentioned, there are two bars across the street which are noisy until the early hours of the morning which can be heard in the front room.
