My fiancé and I enjoyed a wonderful stay at this location during our vacation to Rome!
It is centrally located and within walking distance to the Coliseum (roughly 15 minutes) and the Trevi Fountain (roughly 20 minutes). There are also plenty of small food markets and restaurants littered throughout the immediate area.
The train station is less then 2 blocks away and we were able to go to the Vatican which was relatively about 15 minutes away.
The room itself was very clean and maintained. The bathrooms were clean as well and we did not interact with our roommates often. We also did not have to wait more then 5 minutes for a bathroom if occupied. Just be aware that it is in Rome, so expect to hear cars and pedestrians throughout the day, but it should only bother a light sleeper.
Other then that, our stay was great and we would highly recommend staying here!
