Easy to miss, but a must see!
St. Maria della Vittoria is an easy church to miss in Rome, but you have to ensure you see it while you are there. It's off a side street near a busy Piazza but the Bernini sculptures inside are magnificent! A very beautiful church, quiet and no crowds make it an enjoyable experience. If you find yourself in Piazza Repubblica, head northwest on Via 20 Septembre for a couple blocks and you should find it. There were no drawbacks to seeing this church whatsoever. No street vendors, no entrance fees, and no disappointments!
