Great place: spacious, very clean and centrally located! Claudio (and his sister) were great hosts with good tips and hints for making the stay in Naples a great time. The kitchen had all the basic equipment for our needs, even cookies, coffee/tea and oil were available. Food stores are around the corner in a very lively market-like area, great! We walked from the apartment to all the interesting places, like the historic center as well as the botanical garden, national museum, castles etc. But the subway is nearby, as well as trains to Pompeji and Sorrento (just five minutes walk!). The only downside of the central location might be the (typical) noise floor of Naples supported by a nearby main road. This might bother some sensible travellers, we didn't mind and found this actually authentic.
All in all we had five great days in a more comfortable and authentic location than in a typical small hotel room.
