PLUS : Only 2 minutes from main line 1 and the 2 funicular lines, you can go nearly anywhere directly. Nice trendy area with all shops nearby including a convenient grocery store. Very cheap place for such a central location. More fresh air than downtown Naples. A room inside a garden makes it an interesting concept as you do relax and have your meals there. Responsive host.
MINUS : The area is quite noisy especially considering you tend to leave the window open at night : you do hear the metro in the background in daytime, and in the evening the neighbors in their activities even kids playing. This is very Italian I think not especially a comment for this this place in particular. Also you hear the cars passing by in the street.
I still strongly recommend this place for a short stay on a tight budget where noise isn't an issue.
