We only stayed at the apartment for two nights, but Roberto was very welcoming and helpful by picking us up from the station and showing us the sightseeing highlights on a map that was for us to keep. The communication went super smoothly and Naples historical center is within 15min walking distance of the apartment.
The apartment itself was cozy and clean. The kitchen however was a little under equipped and the neighbourhood a bit noisy at night. But I would definitely recommend this little apartment due to its atmosphere, quality of the items present there (Bed, Bathroom, Kitchen utensils etc.) and proximity to the station.
