I stayed at Luca's place with my fiancee and my parents for one week around Easter this year. It was an amazing time to visit Rome and an even more amazing place to stay at, I would definitely come back here again. The apartment was as described and depicted, except for the smaller bedroom which is lacking a ceiling towards the living room. Everything is very nice, bright, with high ceilings and lots of space. Bathrooms and kitchen are well equipped, and the place is perfectly located: Almost every spot in Rome can be reached by foot.
Thank you also for the great recommendations -- Isola della Pizza was *fantastico*, and we also loved the view from the hills above Piazza del Poppolo! Absolutely recommended!
