Small, functional, close to Centro Termini.
Maria’s place was simple and effective for a first night stay close to the train from the airport (FCO).
I had some extra time after my stay to decide what I wanted to do in Rome for a few hours, and she let me stay around for a bit, which was nice.
The area around the apartment is like most central cities - you’re most likely safe, but it’s a bit run-down. But it is a short 15-20 minute walk to the Colosseum and the Forum. There are lots of great little bars and restaurants around too.
Overall, a good first night stay in Rome. Could be a good main spot if you want to stay a few days and don’t mind not being in a fancy spot.
