This is a surprisingly large apartment in a great location. We wanted to get out of the center of Naples, and be somewhere a bit quieter and nicer. Vomero is perfect for this.
PROS: Apartment is large. Close walk to Vomero center and Metro station. Lots of cafes and small restaurants on the street right below the apartment. Large grocery store right below the apartment. AC works well. Comfortable couch and bed. Also our host was very friendly and responsive. He gave us tips for Naples and a map. We had our hot water turn off during our stay, and he got it fixed promptly.
CONS: The apartment seems like a someone lived here, moved out, and left random things. Not bad, just kind of odd to find. Kitchen could have been better stocked for cooking. Only one spatula, no kitchen towels, no salt, etc. But we were able to cook basic things and purchase items at the grocery store.
Overall I would absolutely stay here again. Be sure to enjoy an aperitivo at the cafes below!
