The apartments are very clean and comfy, besides two bedrooms there is a large fully equipped kitchen. (You may do you stay without visiting restaurants at all, buying fresh Italian delicacies from local vendors).
The house has a superb location, within walking distance to the historical center, but a few steps above the loud and crowded downtown. The direct train's stop to Pompei is like 5 min from your door. The neighborhood looks rather safe in the evening as well.
The hosts were super friendly and were very kind to offer us a lift with their car!
100% recommended for a family/small group stay in Naples.
