Loved Portrait Suites Rome. The rooms are gorgeous and the service is unobtrusive, yet friendly. They have wonderful connections and got me into La Pergola when no one else could. The rooftop terrace is a wonderful place for breakfast and evening drinks. They even tried to help me when a friend had delayed luggage at FCO. I emailed them (having been a previous guest) and they were happy to oblige.
I wouldn't hesitate to stay there again anytime.
