I highly recommend Silvia's apartment! The apartment is located in Pigneto, which is just a short (15-20 minutes) bus or tram ride away from Termini Station, from which you can reach anything in Rome. As a woman traveling alone, I was concerned about safety, but I felt perfectly safe walking through Pigneto at night. The apartment is adorable and very clean. Silvia was an incredible host. She went out of her way to help me, and she provided me with breakfast every morning, which in Italy usually consists of coffee and a pastry, but Silvia had many options. I can not sing her praises enough. Pigneto is not as centrally located to the major sites as some other locations, but it gives you a more authentic taste of Rome, which I appreciated, and again, transportation was easy and quick. (Thank you, Silvia!)
