The pictures online are great, but they don't do enough justice to the apartment. I would thoroughly recommend Francesco's place to any family planning a stay in Rome. We are a family of 2 adults, 1 teenager and two small boys - we had plenty of room to spread out and unlike many other AirBnBs around the big cities (we've used a few), this apartemt felt spacious and everyone was able to get away from each other, if they needed to. All three bedrooms were big and the kitchen was great for us all being able to sit around the table and plan / review the day. The two bathrooms were also very clean, tidy and a good size.
The location (two blocks from Termini - the main Rome rail & metro hub) was ideal. That said, we managed to walk most of the time, as the apartment is an easy 15-20 minutes walk into the main sightseeing areas and once you're there, all the majors stops are quite close to each other.
Locally, there was a good supermarket and some reasonalble restaurant options on the nearby plazza (two blocks).
Francesco met us on arrival and was lovely. He was genuine and charming.
If we do get to Rome again, we would absolutely book Francesco's place again, without a doubt.
