I wanted to check out the Basilica but we got there while it was midday closed so we decided to…read morewalk around the piazza while we waited for the re-opening at 3pm.
We happened to not only be there on a Sunday, but the second Sunday of the month, which is when they do hardware, leather, fabrics, etc. I wasn't necessarily interested in any of that (my preference would have been food on the third Sunday) but it was fun seeing people, especially locals, shop for stuff. It's a feast for the eyes, that's for sure.
That being said, there aren't many newer Yelp reviews for this place but if you are researching this area, know that it is no longer a quiet, more local part of town. This is a full blown tourist destination now and the area shows it.
I'd highly recommend the basilica. The cloisters are gorgeous, with a beautiful garden in the middle. You cannot take pictures inside for some reason, but it's still worth it.
