This apartment is in central location which is close to bus stations and a lot of local restaurants are just right outsides. We walked to Piazza Navona, Pantheon and Trevi Fountain. Vatican is not that far away. Patrizia greeted us at the apartment and recommended a few of good local restaurants.
She was also helped us to schedule a ride for our departure to airport. The driver charged 55 Euro which is about a few Euro more compare to the shuttle service that I originally booked. I cancelled my shuttle service and booked the driver that Patrizia referred instead because we can tell him what time we want and he is on time to pick us up. One disadvantage is that his van is older model and he drove fast so the ride was more bumpy than a newer van that shuttle services had (compare to the shuttles that we were using in London and Paris). We left early in the morning so the driver was just rolled down the windows instead of AC but shuttle services are always turn on AC even we left early morning in Paris. That was okay with us since we are in the early morning.
Also, make sure have some Euro with you to pay Rome tax for staying. I think it is Rome requirement and does not matter you stay in hotel or apartments.
After all, we enjoyed staying at Patrizia's apartment. Thank you for being a great host.
