We really felt comfortable. Our host was really friendly and talkative and the location was awesome as well, because all the sights as well as the metro and a bus stop were nearby.
Don’t set your expectation for the breakfast too high; it’s extremely minimalistic.
The only two points that really bothered me, are the disposable coffee cups and shower gel packages. I would prefer actual coffee cups and a refillable gel dispenser over the disposable ones.
All in one, I liked the place and would recommend it to people who are planning to visit Rome.
