Free parking in Eindhoven?

Hey guys, tomorrow I have a plane to catch from Eindhoven and I’d like to drive there and leave my car somewhere parked in the city. I can then take the bus to the airport. It’s a cheap old Toyota aygo with no expensive things inside so I’m not worried about safety, just looking for a place where I can leave it for free without bothering anyone.

If it’s close to the airport then that’s a plus but not mandatory.
