Massimiliano is a great host, very responsive and helpful. We found the self check-in instructions easy to follow.
The apartment is very central and has a top-rated restaurant right by the front door. It's modern, clean and very nicely decorated with all the amenities you would need on your Naples visit. Only a 5-10 minute walk from all the major attractions and well connected with a metro station down the road. The airport shuttle bus is also just a short walk away.
As other reviews mention, the window is facing a major road so traffic noise is heard mostly during the day, less at night.
If you want to be in the centre of Naples in a clean and modern apartment, I would highly recommend booking Massimiliano's place.
