Giuseppe is a nice host: quick, efficient, and helpful! The apartment is nice and spacious, it has everything you need.
I just had issues with noises (cars passing by a lot and airplanes) not so great for a light sleeper, day and night time.
The location is good if you want to be close to the historic/medieval center and if you need to park the car.
But the port area, Palazzo Real and Chiaia are a bit far away (20-30 minutes drive by cab).
