Be sure and on your walk to Piazza Michelangelo head for the Romanesque church of San Miniato al Monte and walk to the side and stroll through the graveyard where the author of Pinocchio, C.Collodi is buried along with other fascinating folk. Buy some olive oil at the gift shop to take home. Also don't miss the pharmacy located in Santa Maria Novella, it is hard to find because you must step inside a building, but it is worth seeing. They still sell the recipes the monks discovered for beauty treatments for the royalty, buy some almond handcream and go into all three rooms, it is FABULOUS!
Don't miss trying Vin Santo the Italian dessert wine served with biscotti to dip in, tastes like sherry. Every cafe you visit will serve it, it is quite popular!
We had a private driver one day pick us up & take us into Tuscany. His name was Marco and he was EXCELLENT! He provided transportation for the Clinton entourage when they visited. Speaks great English, is quite friendly and extremely knowledgeable. I think it was $360 but you can get half day tours too. We went to Siena,Grieve,San Gimigiano, and Villa Vignamaggio where MUCH ADO ABOUT NOTHING was filmed and did a wine-tasting. We traveled in a black Mercedes and he drove like a dream. It was well worth it, very memorable.
