We are looking to rent a car (National CarRental) to pick up in Florence on the day we are heading out of town for 5 days in the countryside. We are staying near SanGigmanano and want to be able to drive around the area during our stay. I am uncertain which location is best suited for us to pick up at: airport (via Palagio Degli Spini) OR Florence Central Office (I am not sure what that is) at Via Maso Finiguerra. We will be leaving from il Salotto di Firenze B&B at Via Roma, 6. Is one much closer than the other? Is one easier to get it of town from? Are there ZTLs we need to be concerned with? We are planning on dropping the car in Naples before we head on to Sorrento. All help and advice is greatly appreciated! Thank you!
