A friend and I will be in Florence for a few nights in October and have to check out of our apartment at 10am on a Saturday. We will be renting a car to drive out to where we are staying next, a villa 30 min west of Arezzo, to meet up with the rest of our party but check in for the villa is not until 5pm. Initially I was thinking we could stash our luggage at the SMN station (near our apartment), spend most of the day in Florence and pick up our car in the afternoon and head out. But now I am thinking it might be more fun to take advantage of our rental car to spend the day exploring some things on the outskirts/suburbs of Florence or on our way towards Arezzo, or even a little out of the way, maybe by way of Siena. BTW, we are saving the antique fair in Arezzo for the following day when our entire party can go. I looked up some market days in the towns in the area and thought we could have lunch and pick up some fresh fruit and veg for the week but other than that I'm kind of out of ideas. Perhaps a winery, but we will be driving afterwards so I wasn't sure about our safety.
Also any insight into whether these neighborhoods/towns are safe to leave our luggage in the rental car as we explore is appreciated.
I'm grateful for any suggestions you might have. Thanks in advance!
