Genoa Parking Help?

Hello,

We’ll be renting a car to drive from Bergamo to Genoa on the 15th and returning it in Bergamo for our flight back on the 18th. While staying in Genoa, we don’t plan to use the car, so we’re looking for a place where we can leave it parked for about three days and not worry about it.

Do you have any recommendations for free or very safe long‑term parking in Genoa, even if it’s in the outskirts of the city?

Thanks in advance!
