We stayed in Naples for 3 nights at Paola's place. The apartment was modern however
1) there seem to be a problem with ants. Paola sent her father to spray pesticide.
2) shower tray was blocked
3) entrance to the block of apartments is constantly banging throughout the door. Be prepared for that followed by steep narrow staircase to the 1st floor to the apartment
4) The surrounding area outside the apartment is filthy
Overall, worth paying more to Stay somewhere better.
