Thank you. I was asking about today for the mass in honor of the Colombian police academy students. In the end we decided metro was better.
Depends on which Mass you go to. There is a lot next to the church that is free on Sundays. The English Mass is at 930am and a little smaller, so there is usually plenty of space in the lot. The Spanish Mass is at 1200 with more families, so it's not unusual to need to find off street parking near the church.
