The place is as described, if not even nicer when in person, being very clean and comfortable. The bedroom is a semi-private loft area - very cool. The decoration of the apartment is neither drab nor over the top; spot-on to my mind.
The location? You are perhaps 150 meters from the Colosseum. I don't know what could Possibly be better than that.
I've read of "noise" - and note there was an exuberant "gay pride" parade during our stay; following which the bars on the street below were frequented well into, if not, the overnight by partiers. It was a warm evening, we had the A/C on, and must say barely noticed.
Andrea: Grazie mille!
