You won't find much attraction in being out near St. Peter's or the train station. To give advice to the contrary is to mislead new visitors to Rome. There's a place called Alexander Platz about five blocks from the Vatican. Somewhat like an underground jazz club. Some of the best jazz I've ever heard.

It seems quite close to the city on the map and is listed as being at the end of a commuter rail line. We've been asked about Orvieto as well. Perhaps, in the limited sense of the word. Time, to us, is so valuable in Rome. We'd certainly not want to lose time commuting to and from a suburb.
