This location is very much like a hostel in the "lively" Forcella neighborhood. The accommodations were much nicer on the inside than the building appeared, clean Ikea furnishings, accurately represented in the photos. It's 5 floors up and there is no lift. There are 2.4 bathrooms for 4 bedrooms, all of which were very clean. Overall, it was an excellent value for the money and I liked staying there.
The hosts spoke limited English, but were very welcoming and accommodating. Fran even helped me call ahead to my next stop for directions. I think that if I spoke more Italian we probably would have hung out more together. Everyone was polite and respectful.
Breakfast is provided regularly, typical Italian fare of sweets and strong coffee - it worked for me.
Napoli itself is a pretty crazy city. There are a lot of people and they drive like maniacs. This place is walking distance to the train station, which should tell you a bit about the neighborhood... I felt ok, but I'm originally from NYC and of Neapolitan heritage, so I fit in. You need to keep your eyes open and be prepared. The proximity to the station is convenient and if you are looking for the real Napoli (as I was) this is it. Try closer to the shoreline, north of the boardwalk if you are looking for a luxury experience.
