I am struggling with this review because the host was fantastic - friendly, accommodating, and responsive. The apartment was also great - good size, very clean and well maintained. And the location was perfect for exploring Napoli, very close to points of interest, transit, and restaurants.
With that being said, the location was also what made me dislike my stay. It was very loud due to the neighbouring bar and street lights shine into the room throughout the night. The noise and lack of darkness prevented both myself and my wife from having a decent sleep for the 2 nights we stayed.
This is not a negative review of the host or the apartment, but rather the neighborhood.
