My husband and I will be driving into Florence from the Pisa area, to visit the Uffizi Gallery. I have been looking at this site, as well as several others, trying to find the best parking area, outside of the ZTL. From what I can tell, the Oltratrno lot will be our best option. My question is, where exactly is the lot we will be looking for? On Google maps, I see a roundabout directly south of the Porta Romana, and a parking lot directly to the east, as well as another on the north side of the Porta Romana. I just don't want to go into the ZTL, which appears to begin at the Porta Romana. Thank you for your help.
