Parking garage called il parcheggio del borgo, at the back there is a yard where campers etc can stay overnight. The front looks like just a business. Guido showed us our space & gave us a ramp-the ground is sloping. He showed us around (hot water included). We had a key for the gate so we could get back in after 8pm. All this, & electric for 20€. Not pretty but it's about a 10 mins walk into Lucca.
