Paolo's place's location is just perfect, few steps from market, where you can buy or taste local food (really, that should be like your number one goal during trip to Italy) and 7-10 minutes to Duomo. Flat itself if very cosy, we really loved the kitchen in rustical style and nice soft carpets on the floor. Athmospere is really warm, it feels like home. Paolo was super supportive, gave as great advice about restaurants and sight seeing spots. Only one thing you should keep in mind about the place - flat is on 2nd floor and steps are really hight. Just in case, you know, you have big suits or health issues.
Certainly highly recommended!
