My husband and I stayed in 'Apartment in Piazza Navona' for 3 nights early October 2013. Flora, her husband and her lovely son were very welcoming. They were helpful but not invading at all, and communication went smoothly. The apartment was very clean, comfortable, quite spacious, and had all the basics we needed. The only downside I could find was that the lower floor was a bit dark; but who cares, you are in Rome, you should go out! The location was incredible, we never had to take a cab or public transport during our stay, everything was reasonable walking distance. And the price is very reasonable for the area. I would definitively recommend staying there if you are visiting the city.
