This apartment is in a wonderful location: right in the heart of Testaccio, one of the most fascinating and central Roman neighbourhoods. The hosts were also very prompt in their communications, and allowed us to book very last minute. The check-in process was seamless (all automated). Unfortunately the apartment had the feel of a rooming house, or adult hostel, as there are quite a few guests staying there at all times. We personally didn't enjoy this vibe, but it may work for others.
