Everything was perfect here: a nice and simple clean room, with its own bathroom, and access to a living room and kitchen (which I did not use). It is silent and calm, as it is at the end of a street without exit. The breakfast (at a nearby bar) is rather modest. Very convenient distance to the main station, a 15' walk to Piazza Spagna, 30' to Piazza Navona.
Some people help the host in managing the property, and they were available and kind.
