My wife and I stayed at Paola's apartment for an entire week and were very happy with our choice ( It's exactly as you see in the pictures). The apartment was clean and had everything we needed (We cooked quite a bit). The only critique I can give is that there was no TV/cable which was listed as an amenity. Not that you really need tv in Rome(So much to do and see!), but it would have been nice to see the news ect. in the early morning or late at night.
With that said, I think what really made this place great was the location. It's in a fairly quiet neighborhood that is a lot less touristy, but has tons of amenities! There is great dining literally 10 steps away (Il Colibri), awesome shopping, and fantastic grocery/markets. It's also a couple blocks from St Peters/Vatican. We loved exploring this area of the city since we were already fairly familiar with the other parts of Rome.
Overall, it was great. We would stay there again!
