It’s a nice small apartment, very clean, there’s all you need. The neighborhood is very nice, with the very small streets, lots of scooters, and many good traditional Italian restaurants. you really experience Neapolitan life here.
In front of the apartment building there’s a Maradona memorial place with a bar, a nice place to hang out for a while.
The apartment itself is small and rather dark (because it’s situated on the first floor, and that’s rather low considering the high buildings and the small streets. And there’s no balcony. So: go out and enjoy the city, and have a nice sleep afterwards.
