Wow! Just returned from a family trip to Italy, a significant portion of which was based out of Edgard & Jean's wonderful facility. We didn't take over the whole place but had most of it for 4 nights. The location is perfect. All the major sites in the heart of Rome are very walkable. When arriving and departing with luggage we took cabs to Termini, which was maybe $12 euro, but that was for our convenience. So, the location could not really be any better.
The rooms and facility were top notch. We used the roof-top terrace every evening to gather and plan next days events. Of course, breakfast up there was wonderful every morning.
Our whole family cannot say enough good things about the hospitality, location, and quality. Everything was as-represented in the AirB&B post, if not better. I highly recommend this facility!
