The room is bigger than what I thought.
3rd floor with elevator. Breakfast in a nearby cafe down the street, 1 min walk from the apartment.
3 min walk from Termini train / metro station (Leonardo Express, Terravision buses, Metro A & B, etc.)
The street is not particularly noisy but as I like to sleep with the window open, I recommend you use something for your ears if you want to sleep a little bit late in the morning.
Lucia is very friendly even if she doesn't speak English. But conversations being very basic anyway, it was totally OK for checking in and out.
Overall I would recommend this room if you want to stay in this area of Rome.
