Fabrizio's place is very well-located near many great restaurants and some interesting sights in Trastevere. It is the size of a studio apartment but comfortable -- we found it well-equipped and easy to relax in. The immediate surroundings of the apartment are surprisingly quiet at night for how active most of the surrounding area is. The decoration is also pretty charming (love the Pinocchio statue in particular).
We had a bit of a snafu with checking in. We were told that Fabrizio's associate was on his way to meet us, but then we waited without response for an hour and a half. I tried texting several times. In the end, I bought a more expensive data plan, which showed us that Fabrizio's associate had contacted us directly many hours earlier. We then spoke with his associate, who was very responsive. Honestly, things went straightforwardly for the rest of our stay. Might have just been a one-time issue.
