Luca's place was as described in his offer. He was helpful, there to greet me, place was clean, fridge stocked with refreshment... everything was fine. One minor setback is the noise coming from the street and from other rooms in apartment. Seems that the walls are thin :)
But, trust me, you won't have trouble sleeping since Rome will drain your energy through the day.
All in all, Luca's place is highly recommended and for this price you won't get any better in Rome.
