From Rome, we traveled to Florence. It is a more laid-back city with fewer tourists and I wish we had more time to stay longer. The entire city center, with all the tourist spots (except Piazzale Michelangelo which is 30 minutes away and not part of the city center anyway), is walkable. Not much gelato here since we only stayed a couple of days but there is an excellent Aglio e Olio 'round these parts.
