Our stay at Giovanni's place was great. His mom was there to greet us when we arrived, and she was very welcoming (and funny!). The place was very clean and the bathroom was spotless. The mini fridge came in handy for leftover pizza. Giovanni was accommodating with letting us store the bags for the afternoon after we checked out.

I speak Spanish so I was able to understand Giovanni's mom enough to figure out the basics of staying there (key, map, fridge, microwave), but I suppose if you have any other questions and don't speak Italian, you'd have to get in touch with Giovanni.

The neighborhood around the Napoli Centrale station is very busy with lots of men walking around/selling things, so my girlfriend would not have been comfortable there by herself, but we were there together and no one bothered us or hassled us at all, so it felt safe after we got used to the area.

Aside from the busy-ness, it's a great location very close to the train (metro and train to Rome, Pompeii, etc) and there are pastry shops/coffee places right outside.

I would recommend this place, and I would stay here again if I ever come back to Napoli again.
