Paola's place is conveniently located close to Rome's termini station (and metro station) and is within a 21-30 min walking distance to most of the city's major sights.
Her place also has an elevator, which is definitely a welcome sight after a long day of walking.
In terms of safety, my mom and I never felt unsafe walking around at night. Although there might be some graffiti on the walls, the neighborhood is relatively quiet for being near a major transportation hub.
We enjoyed Paola's friendliness and responsiveness to our messages. Could not ask for a more amiable host.
