I visited Rome and stayed in Allesandra's and Nestor's apartment for 2 nights, 3 days. The apartment was at an excellent location, with the metro line A very nearby and the Colloseum at walking distance.
The apartment was perfectly clean, spacious enough for two people, and basically had everything you would need for a short-time stay in Rome! It also comes with a sort of outside terrace, which I imagined slightly different, as I wasn't aware that the apartment was party of a series of apartments and as such that the terrace was next to others in a some kind of inside/outside way.
That aside, I would definitely recommend this place to others planning to visit Rome. Nestor was very friendly, replied quickly, and we could also leave our suitcases behind after check-out, so we could enjoy our last hours in Rome!
