Luca's "Fori Romani 2" apartment is great value. It's a good location, away from the crowds but a short walk from Trastevere, Capitol Hill and the old Jewish Quarter. Also close to Tasteccio, where we did an amazing food tour. The weekend farmers market just down the street is a real bonus. The apartment is small, but has everything you need and is very clean. Cute little window looks directly across to the Palatine Hill ruins! It's also not far from a metro station (but be prepared to negotiate cobblestones & gravel if you have suitcases).
