What are some must-see...little-known places to visit in Rome, Italy?

By Miss_P28Well, I can tell you the Hilton Cavalieri in Rome is a gorgeous place to stay. They have the most delicious Sunday brunch and a great aquarium on the bottom floor.

Oh, plus, there is this little cafe (ok, there are tons of them, but stay with me here) at the Trivoli Fountain. If you're looking at the fountain, take the alley to your upper right side. The first cafe you find makes delicious pizzas and spaghettis!! Don't forget to toss your coins in the fountain.

Do not drive in Rome, those people are crazy!

Ooooh, on the outskirts of the city there are catacombs. This was the coolest part of Rome as far as I'm concerned. Definitely worth the trip -- eerie, cool, and historical!

Plus, if you can get to Venice, I highly recommend it!

You've already received a couple of good answers. One of the best, "little-known" places to visit in St. Peter's is the crypt. Formerly one entered to the left of the Altar and wnet down stairs to see the burial sites of St. Peter and numerous others. Now, you must make a reservation for a time-of-entry. This must be done at least 2 months in advance. The entrance is outside St. Peter's, facing it, walk around the left side past the Swiss Guard about twenty yards to an information window.

It's an unusual site to visit that most tourists overlook.
