Brilliant location in the centre of Trastevere, but also very short walk to the bridge over into Campo Dei Fiori or along the river pedestrian towpath to Vatican, or tram stop 8 at Belli, or up to the Forum.
Obviously a small appartment, but with glorious terrace on two sides, masses of light and air, and you'll not spend much time there anyway since you're in the middle of Trastevere
