Parioli Rome is a charming sim with shops, cafes, and a great information center build. I found myself wandering through again and couldn't resist stopping at the ancient Boca della Verita (Mouth of Truth). You'll find it in the alcove fountain. I remember the scene from one of my favorite movies, Roman Holiday, when Gregory Peck sticks his hand in and pretends to have it bitten off (one of the legends that happens if you lie), a practical joke that makes Audrey Hepburn scream in surprise.
Parioli also has a beautiful build them that for used for an international information forum. It's a gorgeous building and worth checking out for the details alone.
