We stayed at the apartment for one week and the place was amazing. The apartment is right in the middle of the old town close to restaurants, sights and shops. The apartment itself is incredibly well furnished with everything you could need (AC, TV, sofa, dinner table, well stocked kitchen etc.). The apartment is also very spacious for its central location.
I would also like to note that the communication was fantastic. Rino replied quickly and we also spoke to Deborah who was able to help us through our stay. We did not meet Rino, however Rino's father was there and was very helpful; so much so that he kept our luggage safe after check out and booked us a taxi to the airport.
I would fully recommend staying at this apartment and would love to stay here again upon my next visit to Naples!
