I feel like no matter what I say I cannot describe how great Stefano's place is. The apartment was comfy, clean, colorful, and well-maintained. There was juice, water, milk, espresso, butter, yogurt, bread, jam, and fruit provided when we got there. All the beds were clean with colored sets of towels for each person.
Stefano met us at check-in and was very friendly, giving us tips on how to do what we had planned (Pompeii, Herculaneum, Vesuvius, Capri, and the Amalfi Coast) and provided a map of Naples he had made for the apartment. It showed the apartment with suggested restaurants, locations of museums, churches, and transportation. He also provided lots of pamphlets from the museums in the area and had even picked out the ones that applied to what we were planning on doing.
He messaged me during the weekend very friendly asking how our trip was going and let us stay well past the checkout time (our train was in the afternoon).
I seriously have no complaints about the apartment. 5 of us were staying there and we didn't feel cramped at all and we were all able to use the shower without a problem with the hot water. The apartment was an easy walk from the train station and the restaurants Stefano suggested were delicious and reasonably priced. They felt like local places but were friendly to us.
Everything was terrific. Do not stay anywhere else. You will not be disappointed with Stefano's apartment.
