This is a lovely little guesthouse. It's in a great location, within immediate vicinity of shops, restaurants, metro station and of course the Trivi Fountain.
Inside it has the smallest lift I've ever seen, wonderful rooms with well sound-proofed windows; shower and wash facilities are great; bed is comfortable; and the whole place is spotlessly clean. I would definitely stay again and highly recommend it.
I would also point out that one of the hosts, Macarena, reached out to us before our visit to get our arrival time and offer transfers, if we hadn't already booked. On arrival, she also sat with us and highlighted other places to see, good restaurants and which bus or metro connections to make.
