Renato's place is a very nice and spacious apartment with a lot of charm. It is big enough to sleep 8, so with the four of us we had plenty of space to spare. Check in and check out was very smooth, and the whole place was very clean. Although the apartment itself was very nice, the best part of it was the location. It was right behind the pantheon, and pretty much everything was in walking distance (Vatican, Roman Forum, Trevi fountain, Piazza Navona,...) were all within easy walks from the apartment.
So certainly a place that I can recommend for larger families!
