Our host, Veronique, was excellent in her communications with us before arriving: she sent us a map to her apartment, directions on how to get there from either the airport or train station, and gave us her cell phone number. When we arrived she met us and showed us around the apartment. She had left us everything we needed to immediately feel at home -- bread and jam, snacks, drinking water, soap, towels, electrical adaptors etc.-- and ready to go out and explore her exciting district of Naples. She also left us an extensive writeup on what to do / not to do in Naples, her recommendations of places to see and eat, and brochures on Naples and the surrounding area.
Though small, her apartment was comfortable and quiet.
When leaving, we needed to reserve a taxi to pick us up at the ungodly hour of 4:30am. Veronique arranged for a taxi, which was waiting for us at the exact time.
In short, we were very happy with our stay there. Veronique and her apartment were everything we could have asked for.
