Would definitely recommend staying at Valentina's apartment. Very nice and clean (they have a service come in after each stay) and can't beat the location! Right next to the forum/ coliseum and other nearby churches (e.g. San Clemente). The area surrounding it also has plenty of good restaurant options. Valentina was not there during our visit but was very quick to respond to any questions we had and was very accommodating. Her brother picked us up from the airport and was very helpful giving tips about the city. Again, gets our highest recommendation and had a great stay in Rome!!
