The room where we stayed was very well decorated, clean, and with a great private bathroom. The common area was also very stylish with all the facilities we needed. Because we got cold weather in Rome the heating was not warming enough the room but it was okay, anyway.
Although the neighbourhood looked a little doubtful, it was good to be outside the crowed center. The proximity to some public transport like Roma Trastevere Railway Station was very good. To reach the center by foot it can be too much but there are also bus choices.
