I highly recommend Nadia's apartment as it is very central in Campo dei Fiori. Most of the main monuments (Colisseo, Pantheon, Fontana di Trevi...) are within walking distance. Therefore, we didn't take any public transport during our 4 day trip to Roma which was very much appreciated given the busy cities we live in. The apartment was also very clean, nicely decorated and had all the facilities we were expecting. We enjoyed having a late dinner in the nice terrace as well. Nadia was not in town but both Joel and Renato were very nice during the check-in and check-out.
