Sergio's place is very close from Roma Termini train station and within walking distance of the Colosseum. There is also a metro station nearby. As other reviews have stated, there was a bit of noise from the street traffic that could be heard from the room at night and early morning. As a light sleeper, it didnt bother me too much. Sergio provided clear instructions on how to get to the Airbnb and provided suggestions on things to see and do nearby. The only thing that wasnt perfect was that there was a strong sewer smell in the bathroom. So I would recommend keeping the bathroom door closed when not in use. I would recommend this to others and I would stay here again.
