We really enjoyed staying at Gian Paolo's apartment. He was very welcoming and he provided fruit juice and fresh fruit on arrival as well as a folder with recommendations of places to eat which we found very useful. The apartment itself was spacious and perfectly sized for our family of 3 to stay. The apartment is in a great location - it really is very close to the Colosseum and Monti is a lovely area with nice bars and restaurants to eat in, which don't feel overly touristy - we particularly enjoyed eating in Il Tettarello which was around the corner from the apartment. The air conditioning in the apartment was particularly great during the very hot days in Rome in August and Gian Paolo had plenty of books and DVDs, which kept us entertained when we didn't want to venture out into the heat of the afternoon.
Some things that we particularly enjoyed doing in Rome were a free walking tour one afternoon (Rome's Ultimate) and a day trip to Castel Gandolfo (40 minutes on the train from Termini) where we had a wonderful meal in Arte and Vino, and went swimming in the lake in the late afternoon.
We would highly recommend staying at Gian Paolo's apartment - the location is fantastic and he provided everything we needed for a very pleasant stay in Rome - Thank you!
