My wife and I stayed at Piera's accommodation for 3 nights and found it to be very beautiful, clean and convenient to train station, tourist sites and metro station :)
Piera is a very friendly and happy host. She greeted us and gave us a helpful run down of what go see and where to eat in the area - this was great and very much appreciated! Also the breakfast area was stocked with complimentary coffee and croissants; win!
First impression of the area was a little sketchy but we never had any problems.
All in all, a pleasant place to stay in Rome :)
