Location, location, location. It's a very short walk to St. Peter's Square and St. Peter's Basilica. Right next to the Vatican City Wall and the Vatican City museum. It's also only 3-4 short blocks to the Metro underground subway station and one train ride to the Colosseum. Lots of shops and restaurants in the neighborhood to walk to. Great location.
We stayed at Luca's apartment in Rome for 4 nights. Looks just like the photos. It's on the 3rd floor of a building with an elevator. I did not get a chance to meet Luca, but we did message each other quite a bit. He did arrange private car and driver from FCO airport to the apartment for 48 euros (the current rate as Oct 2016) each way. Wifi works great. We had a terrific stay in this 1 bedroom apartment in the heart of Rome. Highly recommend.
