Andrea and his place are both excellent. 3 minutes to the Colosseum and the metro, bus, and tram. The apartment was perfectly clean and a great respite from the hot afternoons. Self checkin was easy.
Again, the location is great. We walked to and from Trevi multiple times, including very late at night, and it's a great 25 minute route that passes the Colosseum, forums, and the Altare della Patria. Especially nice at night or early in the morning.
