Here is the compact area of sites to visit near the Piazza Farnese in Rome. The Trastevere neighborhood is just across the Tiber, and the Jewish quarter is just to the east of the map. The unlabeled dot is the Teatro di Pompeo, Pompeii's theater. There are many restaurants within a short walk of the area; some of the best innexpensive places are near the Campo di Fiori.
A walk down the Via Giulia is quite rewarding. At the end, after crossing the Tiber, you'll come to Vatican City.
