If you want a truely Roman experience, try Stefania's appartment in an old palazzo. The inner courtyard is cool and there are stairs, a spiral staircase or a lift to the first floor. All the main rooms have high ceilings and tall windows. Two bathrooms and a well equipped kitchen (first stop bottle opener). Very comfortable beds, pillows and lovely cool sheets. And no noise from the streets below.
But the real benefit is that it is among the little streets a few minutes from Piazza Navorna, with a host of bars, cafes, restaurants and gelati shops. There is also a small convenience shop opposite with a friendly proprietor. Take comfortable shoes. We walked to the Vatican, Borghese Gardens, Trevi Fountain and Spanish Steps.
