Booking: From the first time I contacted Silvia until check in, she was extremely responsive and helpful. She answered all of my questions quickly.
Location: I like to be near public transportation and Silvia's home was accessible via Metro (2 min walk) , Tram ( less than 10 min walk) and bus. You can walk to Rome's Termini train station if you want but its faster and easier to hop on the Metro for one stop. The location is perfect for accessing the sights and then getting away from the crowds at the end of the day. The apartment is not located in a touristy area and I enjoyed being amongst locals. I even made friends in the neighborhood. As others have mentioned, there is street noise. I am a lite sleeper and was fine with ear plugs. My friend didn't need to use any. It's typical city noise and nothing over the top.
The Apartment/Check In: The apartment was very clean and is a good use of space. Each room had its own air conditioning unit but even in the hot August heat, the apartment never got uncomfortably hot. Silvia and her son met me at check in. English is not her first language but she was very excited to welcome us to Rome and tried her best to have conversation with us, she is a very sweet woman. She brought us breakfast and was there to answer any questions we had, she also left pastries for us to eat during our stay. Her son is fluent in English, was extremely helpful and explained different features of the home as well as gave us suggestions for places we may want to go to in the neighborhood (ie stores and restaurants). They also provided a resource notebook that included directions to the main attractions as well as things like the location of the nearest hospital and other emergency information.
I would definitely stay at Silvia's place again.
