Perfect location! We stayed here and absolutely loved being right in Trastevere. There's so many fantastic restaurans right around the corner that we spent most of our time in the area.
The apartment itself was pretty good for the three of us, and despite being on the ground floor it was pretty quiet.
It does get a little damp and musty though, but not enough to bother us.
The rooftop terrace was great, and nice that it's shared if you want to talk to other guests etc.
The biggest down side for us was the communication on the day of arrival. Despite many messages we hadn't heard back to confirm check in details for keys and had to make our way to the apartment very unsure whether we'd get in. After an hour or so we luckily caught a couple guests on their way out who gave us the phone number for Paulo who saved the day. He was so lovely and helped us through the set up that it almost made up for the earlier issues.
