It is a well located place, small but nice, two blocks from city center. You must to leave the car outside the city walls, there are places to pay showed in blue or not payed showed in white, take the luggage and climb up to the ramp. It is not hard. Don't try to get there with a GPS, you will have problems to get out of the small street and maybe is prohibited. Cars are problematic in Italian medieval cities. Antonella and Alessandro are very kind.
