Not only is the terrace and are the views from Nino's place extraordinary, but the apartment itself is a wonderful and pleasant surprise. It is huge and very well decorated. There is lovely and unusual art everywhere, with the walls painted in various striking and cheerful colors. The place is light, airy and quiet. Also, the location is superb. It's in a neighborhood that is chock-full of character, is uniquely Neapolitan, close to the metro and other means of public transport, and is an easy walk into the heart of the historic district of Napoli. Furthermore, there are a few restaurants nearby that should not be missed, either for their foood, or for their unforgettable ambience.
Nino was excellent in communication. Although we did not get to meet him, his friend was waiting for us there when we arrived and was quite flexible with the timing of the check-in. I most highly recommend Nino's place.
