Federico did not show up, instead there was a lady who didn't speak english very well, but gave us enough information for us to know how the "flat worked" and where to have dinner. The flat is as described, clean, and within 10 minutes walking from Colosseum. The only not such good thing about the flat is the fact that it is an old garage, so the door is straight to the street. This means there's a bit of noise and clarity, which will prevent you from sleeping after sunrise.
