Very close to the Termini (walkable with a small suitcase), so it's convenient if you are departing from that station. Generally though, if you are staying in Rome, I would not want to stay in that area. It was a bit dirty, and just scary at times (at night, I wouldn't feel comfortable walking home, especially alone).
Breakfast is supposed to be included, but it was not. The restaurant downstairs was closed and there was no reimbursement for it.
The door to open the main apartment door is hard to open, and if it weren't for other guests that came in to help us open it, we would have been stuck outside.
The apartment is clean, but dark and has a 'cold' feel to it. Glad we were only there for one night--in late, out by morning.
