I don't think we can say enough positive things about Ilaria's place. First off, Ilaria and her son met me in person and showed me the place. They had also made a list of recommended restaurants (which were all great) and other things to do. They both couldn't have been nicer.
The place is adorable and was perfect for the three of us. And, though we hadn't thought it a big deal when we booked, the wi-fi was a godsend.
As others mentioned, the place is right in Trastevere, close to everything. But it isn't in the loudest part of the neighborhood. Though we found it charming, folks outside can be jovial until late in the evening. Not obnoxious, just present. But that's no fault of the apartment!
Ilaria helped us find a great ride to/from the airport and checked in with us often. It really couldn't have gone smoother. We'd stay there again in a heartbeat.
