We really enjoyed our stay in Fulvio's apartment, which was comfy, clean and perfect for us 3. We liked being both close to Trastevere and Testaccio and a quick tram ride away from piazza Venezia. We were shown in by Fulvio's friend Federico. Check-in and out were perfect, especially that we could arrive and stay a little later than the "official" times. Also communication was easy and very quick.
