The place is located very conveniently, 15 minutes walk from Termini station, and even closer to Coliseum. All famous tourist places are within walking distance, except for the Vatican, maybe.
The place is clean and quiet. I must now that other guests can sometimes be noisy, and you better have your ear plugs ready for this case.
Guido - the host - is very friendly and helpful.
The breakfast is offered right outside of the house, 15 meters from the door, really close. It is of great quality, no complaints whatsoever.
