It is several years ago now but I have stayed there and I thoroughly enjoyed my stay. I won't talk specifically about the rooms etc as I know it has been refurbished since but the room I had was a comfortable, single room with shared bathroom facilities - fairly studenty alright. The best thing about it is the location, the building is beautiful (and looks like it has been lovingly restored), having the central courtyard is just wonderful after a day's hurly burly in the city and it is literally a stones throw from the Pantheon. Would I recommend it (even after a few years remove)? Absolutely!! Oh and when I was there, the oddest thing about the place was that the kitchen was staffed by Polish nuns, I never found out why...
