Nice flat in a very good location. To the vatican it is only 10min walk, we liked walking everywhere and the main sights are a max of 1,5h walking distance. The trasteverde quater with bars and restaurants is around 45min (walk) away. Restaurants and Cafés are also right around the corner of the flat, as well as supermarkets.
The flat itself is nice and has very comfortable beds. For light sleepers it might be a little loud at night. We missed a little kitchen or at least a fridge.
Contact with Paolo and Lisa was easy and friendly.
