First: Location was absolutely perfect! I have stayed at many points of the city and now could not imagine anything being better than this. Walking distance (and I mean easy walking) to Saint Angelo, Vatican, St. Peters, Navona, Campo, Pantheon, Trevi and Steps (yep... that is pretty much the biggies). Taxi stand and bus stop are directly out the front door for Colosseum, Foro Romano and the uttermost parts of Rome!
Communication was fantastic in every way and the apartment is spacious, well equipped and rather museum like.

Fantastic stay, I would certainly book it again!
