Unbeatable location a couple minutes away from the bustle of Campo de Fiori (fortunately, the hordes of tourists mostly stay there and leave the streets behind it marvelously untarnished). The room is very quiet (with a window into an internal courtyard), with gorgeous antique furniture and paintings, plus a frescoed ceiling! Ideal place for a solo traveler looking to be very centrally located.
There is a faint smell of cigarette smoke in the apartment, so please be aware if it bothers you. (didn't bother me)
Charlotte is a great host, was very good about communication and check-in and check-out arrangements and provided great local recommendations.
