Marco is a wonderful host, and his place is lovely to stay in (we were there for 4 nights in late June 2016). Great terraces, working a/c, plenty of water pressure, a modern elevator, and a clean and well equipped flat. The location in Chiaia is just about perfect if you want to be in the center of town, but although central it is not noisy at all. If you have any issues with stairs (the bedroom is a loft), however, this is not the place for you. Otherwise I highly recommend it!
