We had a great stay at Carlo's place in Trastevere. It was a little farther out of the hustle and bustle of trastevere but it was well connected to public transport so if we didn't feel like the climb up the hill we could easily jump on a bus! There wasn't much in the immediate area but it wasn't far from life, it was safe and the apartment was clean, practical and well equipped, airy, bright and great for a short stay.
