We arrived in Rome from FCO and arranged to meet Gianluca at "our apartment". He was there waiting for us, and showed us around pointing out all of the features, and familiarizing us with the neighborhood. He was extremely cheerful and nice. There is a 24hr Carrefour Supermarket about 2 blocks away, as well as the 64 bus route which gets you just about everywhere you want to be in Rome. Gianluca lives nearby, we stayed for 2.5 weeks and during that time, ran into him on the street a least 2 or 3 times. The apartment was clean, and has a great terrace that gets morning sun. We used the washer to do laundry and then hung our clothes on the dryer rack. You're really close to the Vatican, and just beyond that is the "farmers market" - Mercato Trionfale (great for fresh produce, and high entertainment value). For the most part we walked everywhere, you simply cross the Tiber, and you're there. We walked on average about 5 miles a day. If walking is not your thing, the 64 bus comes by very, very frequently. The apartment was quiet, and the bed comfortable. We cooked dinner about 3 times per week, and then hit up some of Gianluca's recommendations.
We would definitely stay here again next time we are in Rome. I also appreciate that he helped get car service back to FCO since we were leaving for a very early flight, and the trains would not be running.
