Flat is very spacious and bright, exactly like on photos, excellently suits travelers with children.
Located very convenient - just next to the border of ZTL area - so very central, but at the same time no problem to arrive/depart by car. Area is very safe and quiet, there is a couple of smaller grocery stores nearby, and a big one just 5 minutes walk. Center of the city is just 10 minutes walk along a beautiful arcade-covered street.
Giulio is super-welcoming, and made both arrival and departure very smooth and pleasant (on arrival he was waiting for us near the house, and on departure let us keep luggage in the apartment and organized taxi to airport). He also gave us perfect advices regarding sightseeing and dining - we literally had the best meal of our Italian holidays at one of places recommended by Giulio. Overall highly recommended.
