Good experience, lovely rooms with helpful staff in great location. Central enough to walk the majority of what we wanted to see - Colosseum, Vatican, Spanish steps, Trevi fountain etc very nice breakfast served in rooms and safe feeling situation with 2 coded doors before you are inside the residence.
Only 2 letdown - I don't know what is meant to be "soundproof", but I could hear every room, every footstep outside, and the people who lived upstairs. And the elevator - while a charming little original feature of the building - did NOT fit our stroller or luggage.
