Fantastic trip to Naples. Paola & John were wonderful hosts, very helpful and welcoming, the apartment is located in a beautiful building, typical of the area (and I'd say of Napoli).
The location is very practical even though the neighbourhood is pretty quiet but in 20min you can join the beaches (Bagno Elena or Giuseppone a Mare), the ferries to Ischia, Procida, Chiaia, the train to the Vesuvio or Pompei, the nightlife of Vomero/Materdei or the Centro Storico.
Don't hesitate.
Thanks again Paola & John.
