Raffa is a very nice host, unfortunately I was dissapointed about the flat, as it is located on a not very nice street, where additionaly to that, is a very loud and strong traffic, stops at midnight and starts with the tram at 5 am, so I didnt sleep much. The flat is quite nice but not a place where I would spend much time. If you don´t mind noise, it is well located close to the Coloseum but be sure you are not walking alone back in the evening after 9pm.
