Great place.. the location is the best thing, it is really just 7-8 mins on foot from St. Peter's square. Very clean and in a nice old building. The host was very responsive and always ready to help. One slight problem is the phone network and mobile data but that's mainly because the apartment is located underground level so make sure to keep your phone near the windows. Totally recommend this place especially if your stay is for exploring Rome and for tourism as its location is superb.
