Thanks for writing to CiaoMilano :-)
Most public parking areas in Milan are managed by the local transport authority, ATM. (The ATM parking management
reads this message in Cc:)
One of the ATM parking areas - which is in Via del Burchiello, close to the subway station Pagano - can be used by tourist buses, too. This parking area is outdoor, and not patrolled.
Here's the relevant page
in the ATM website. Unfortunately, this page is currently in Italian only.
The fare - as you can see - is Euro 6 per hour.
Details - unfortunately, in Italian only - and a map are in a downloadable pdf document.
If we can be of any further help, please let us know. Do not hesitate.
Welcome to Milano :-)
