Silvia and her son John Marco were absolutely fantastic. They are so helpful and willing. We stayed 5 nights in their apartment. It is a perfect location, 10 minute walk to the metro and maybe another 10 minute train ride to the city center. There is also a bus you could take that is 30 seconds away from the front door. Apartment was very clean. And again the location, it's in a beautiful and historic neighborhood, very quiet, very safe, and if you don't speak Italian it is a fun time with the locals. They are very polite, but most do not speak any English. Also the best coffee and italian food we had in Rome was near the apartment, not in the city center.
Definitely recommend!
