Fantastic little place. Very close to the station (Napoli C.le). Host was very kind and the little room that I stayed in had all the items you would need in a small apartment (i.e. fridge, kitchen, washroom, wifi, and AC). The wifi was a bit slower than I'm used to when compared to my home, but at least there is wifi to get online and checkout locations without any issue. The hallway to get into the place is quite dark, so at night it is a little dark.
My little advice for this place is that, if you are coming from the train station (Napoli Centrale), please please avoid Piazza Giuseppe Garibaldi as that's where all the pickpockets are waiting. They will know right away if you carry a luggage and will creep up behind you if you have a backpack. This is a much of a worse issue if you're coming during the mid-day (afternoon/evening); however, if you can go through Corso Novara street, which I think would be much safer to go through.
