Beautiful apartment, and very convenient for wandering to the tasty restaurants of Trastevere and across the bridge to the sights of Rome. Very easily reached from Termini on one bus (H).
Fabio and his sister Barbara were great hosts, making the checkin very easy and texting to make sure we had everything we needed.
One comment - the flat would be a challenge for light sleepers as there is a lot of traffic noise until midnight, and starting again at about 6am. Given how much we walked each day, this was not an issue for us!
