We just finished a 5 night stay at Roni's place and absolutely loved everything about it.
The location is ideal, in the heart of Chamberi, with coffee shops, bakeries, supermarkets, and restaurants (including the must try Peppe Fusco) all within a short walk.
The place itself has a wonderful open air feel to it, with a loft (that my teenage daughter loved), and outdoor rooftop patio that we spent all of our mornings and late evenings.
The place is probably ideally suited to either a couple of a family with smaller children.
