We just spent four great weeks in Giacomo's apartment, beautifully situated for exploring various Roman neighborhoods, including the Prati neighborhood near the Vatican.
Giacomo picked up up at the central train station, a very generous gesture since this meant we did not have to worry about getting to apartment with luggage.
The apartment is very comfortable and has a lovely small terrace, quiet and private, perfect for having a coffee, glass of wine, or a meal.
The area between the Spanish Steps and Piazza di Popolo is full of cafes and restaurants, grocery stores and delis, and the apartment is between two Metro stops and almost right next to a very useful bus stop (the small electric 117 going to Piazza Venezia and further).
