We had a very good stay at this place. The flat is very nice, spacious, and clean. If you are really very very sensitive to noise, you can hear a bit the street at night, but it wasn't at all a problem to us. Paoloa is very kind and extremely reactive to any question.
The location is great, near the everything, the shopping area and the historical center. Since you are in the center of the city parking for a day is 25€/day if you stay in the streets near the flat. That's what we did since we were there only for a day. There are other options for parking in other places of the city.
We definitely recommend the place.
