We had a great stay. The location of the flat and its accessibility at the ground floor were the main selling point for us. We travelled with our 4-year old son and our 3 months old baby, so we had a pram with us and it worked fine with the flat. The flat is not really in piazza Navona, but closer to Castel S. Angelo, maybe 10-15 minutes on foot from Piazza Navona but it didn't disturb us. Elena organised us a travel cot, which we found very comfortable. There is a fantastic café less than 10 minutes on foot away, Emporio alla Pace that we strongly recommend for breakfast, given the friendliness of the owner, the quality and the more than honest prices. In that area of Rome it is absolutely fantastic. The only minus point of this flat is that in the master bedroom there is no wifi signal.
