We have been going to Rome once or twice a year to visit the university, staying between one week and two months at a time. Pamela's apartment has been our favorite place to stay and will be our first choice next time we go.
The apartment is within a five minute walk to Termini and a fifteen minute walk to the university. The bedroom is perfect for sleeping: quiet, dark, and cool. The apartment is on the top floor of the building and includes a nice rooftop terrace with a view that includes the tops of Santa Maria Maggiore and St Peter's, with the Apennines in the distance.
There are good restaurants near the apartment. I recommend Culinaria for a nice dinner out and Trimani for a more casual meal or aperitivo, with fantastic wine.
