The apartment is very clean and spacious. You have access to most accessories like hair dryer, cooking utensil and washing machine, with place you hang your clothes. Nice good bathroom and good AC and Wi-Fi.
And host was nice to leave complimentary snacks and water and juice in the refrigerator.
The only downside is that it’s 15 min walk away from old town.. There’s is bus station not too far from the apartment (4 min walk)
But I found public transportation quite bad in Naples compared to Rome.
I also recommend eating breakfast close to the market (clothes fruits , meats )very near the apartment. From a place that has its food cooked and you point what you want. You eat for less than 10 euro including soft drinks for 2 people and it was delicious. Rather than buy it in overpriced place in tourist area.
Or just cook at the apartment.
