We stayed there for 3night, the room was enough and bed was comfortable to sleep. We could make our own food and coffee there and all the kitchen stuff was very useful. The area was very quiet and safe. Very convenient to get groceries from the market right down the street.
However, the house wasn't "entire house" like it described but "shared house/room with bathroom" if someone want to have private house with own living room and stuff; better stay in different place. It was little far from the main streets of Trastevere(about 25min) but close to the train station.
Overall I recommend this place.
