Parking is a problem, there is only street parking and that is at a premium. The church is open before Hl Mass, therefore you can visit between Masses on Sunday. The church is absolutely gorgeous. It was voted most beautiful church in the USA in 2016
I'm not sure about visiting times. As for parking there is a small lot in front which fills up fast, and also a lot behind the church. You drive around the block to get to that one and turn into the gravel driveway next to the vet clinic. There is also street parking along the surrounding streets, which you don't have to pay for if it's a weekend.
