Parking by porta romana florence

I found parking in a small piazalle at porta romana convenient many years ago. We are staying south of Florence (near impruneta) again and would like to park there for a few early mornings sightseeing in Florence. Curious if anyone knows if it’s still out of the ztl zone or has any other knowledge of parking in the area. I believe the ztl begins once you cross through the porta into the city. Thanks!
