Don’t even think about using a car in the city. Distances are small, public transportation is efficient, and parking is a nightmare; so stash your car in a private garage until it’s time to leave. Culture mavens should look for the annual Settimana dei Beni Culturali in April when all the state museums throw their doors open and offer free admission for a week. And consider a visit in the off-season (November through February), when prices are lower, crowds disappear, and locals are more relaxed.
