We're planning a visit to the Florence/Sienna/Cinque Terra area and would like to rent a car for the Sienna/Tuscany area. What is the best way to get from Florence to Sestri Levante and from there to Sienna? Is there a train out of Florence? Can we rent a car in Sestri Levante and use it for several days in Sienna and the surrounding area? Would appreciate any help with this ... also planning several days in Venice, but will work that into the rest of the time we have. Thanks!!
