2 big spacious bedrooms rooms. The living space is a bit dark, but we were out most of the day so not an issue for us, bit could be if you were planning to stay inside... We've stayed in Testaccio several times when visiting Rome. This place is great, really really quiet. It's off of the main road which I found better in terms of air quality, and really nice to be able to use the courtyard in the middle for our little girl to play in. There's a kids play area close and evenings spent at the piazza.
