We are coming in March and will have 5 nights in Florence. My husband would like to rent a car to travel to the Chianti area and also the hill town area south of Sienna. Is it possible to rent a car for a day and drive south of Florence into the country? We have stayed in the Tuscany area on a previous trip but had rented a car in Pisa. I know that it would cost more to have a car just for a day, but he'd rather do that then deal with parking or do a tour. I see a number of rental places on google maps on Borgo Ognissanti. Is that location the best?
