The apartment was perfect - very clean and neat, with nice decorations! I think was recently refurbished as it was looking like new. A bit cold begging of February, but they have an electric heater you ca use (AC was not blowing enough heat or was not working on heat mode).
Area is not the best, walking distance to main restaurants in the city center is 45 min, bus station is close, Napoli Centrale is also close. Apartment was perfect - location wise I would choose something closer to the city center if is in your interest to spend time in that area.
