Valentina's apartment was fantastic: good location, quiet, clean. Also having air conditioning was wonderful for a mid-August visit :)
The location is near the Lepanto metro stop and is about a 10-15 minute walk to the Vatican and is also close to the Piazza del Popolo and Villa Borghese. There is so much to see in Rome and we found in to be a good central location for our visit.
Valentina was very helpful with recommendations and logistics. I would highly recommend you check our her place when in Rome!
