The apartment is very "gemutlich" (ie, comfortable) and located next to the city park called Villa Comunale next to the shore. The piano, which I had the occasion to play, has a very good sound! The same applies to the sound system.

A seven minutes walk away you can find the metro station of Piazza Amedeo where the trains leave for either Pozzuoli or the central station of Naples. It is easy to catch taxis from the Riviera di Chiaia. There is also a bus stop within a five minutes walk, but I didn't use the bus since you never know in Naples when they stop by, but this is a different story... In short, the location is perfect for trips to neighbouring places and, of course, to the interesting spots of Naples itself.
Right next to the apartment there are plenty of bars and restaurants. Groceries can be bought at stands on the Riviera di Chiaia. Some five minutes walk away, a little bit up the hill, you can find a small supermarket and other shops. The neighbourhood is middle-class and safe. Even long after midnight there are a lot of people sitting outside at the bars.

Only suggestion would be to get a bigger caffettiera which would help to make coffee for TWO persons instead of for only one ;-)

Although not being there in person, Luigi was always accurately answering to my questions before and during my stay.

To sum up: who's interested in Naples and surroundings AND an accommodation with an excellent cost-benefit ratio shouldn't hesitate to rent this place!
"Dieci e lode!"
