Fab's flat in Trastevere was so lovely - such a sweet and convenient location. If you're at all sensitive to sounds, note that while the windows block out much of the sound, you'll still hear the rowdy folks on the street at some times. It's an easy 10 minute walk to Campo di Fiori and all the wonders that await - I didn't take a taxi or use transit once outside of my airport transfers. This place has everything you could want for your Roman vacation!
