You will have found the Shangri-La of Naples if you stay at Giovanna and Carlos apartment. The space is beautiful decorated and laid out. You are right in the heart of town but the walls and shutters are so old and thick that you don't hear the noise once inside.
A fantastic Museum is right on your doorstep and everything is pretty much in walking distance, and if your legs are tired the metro is around the corner.
One of the best features of this experience was the delightful Eduardo, he was absolutely charming and provide some amazing advice on food places and areas to visit.
