The appartment of Rosanna is really nice, clean and well located (only 30min walking from the colloseum, there are guides of Roma and Rosanna gives good adresses of restaurant and everything, but we regret the lack of privacy in our room, there was a window glass on the door of our room which led directly to the bed, all who passed in the corridor could see us (although it is blurry), the same thing in the second bathroom: a window looked directly onto the shower, while showering I could see people passing in the corridor.
Another negative for us was the shower, we had to wait at least 15 minutes for hot water, and again there were blackouts.
Except that everything was fine. We still recommend.
