We stayed in Luca's flat for three weeks, and it was home for us during our stay.
Everything was as described, and the place is perfectly located in the city center, near O'Connell Street, or the Trinity College. Despite the flat is in a busy street, the windows are good to make it almost noiseless.
The flat was very clean. Actually, I think that the carpet is the cleanest one that I have ever seen in Ireland and UK. The dryer was not working, but the clothes dryed in the hanger without too much problems.
Although we did not meet Luca, he did his best to ensure we have a perfect stay, being very responsive at any time.
I would recommend the place, and we will return in case we go again to Dublin.
