Nice appartment with the basic inventory.: everything you need incl. WiFi.
An Nespresso machine and something to foam milk would be an add-on. ;-) Owner is very helpfull.
We stayed as a family with 2 kids (10 &12). Great walking distance, we did everything on foot (trainstation, Harbour, shopping streets, etc). Bakery at entrance of building and across the street. Also try Buonomo for dinner at the Main Street: honest Napoli food for a fair price. Also for take away.
