Very nice apartment, just like described and seen on the photos, wifi, air conditioner, toilet, and hot water worked well. Also the location was very good, safe, close to the metro, shops, and restaurants. Mario greeted us and provided everything we needed immediately, he responded quickly, gave a lot of advice and was very nice. He also gave us breakfast vouchers for cafes around the corner (which we didn't use because we don't eat breakfast, but still good service!) At check-out we met Emanuela, Mario's wife, who was very lovely and caring. We would definitely recomment Mario's place for Naples, even for a longer stay. :)
