I stayed for two days. The location is good, a short walk from Napoli Centrale and besides the old town. Marco was a fantastic host - he arranged an airport transfer for me, kept me updated with all of the important details and recommended lots of things to do, local tips, and some amazing restaurants, including two of the best pizzerias located within ten minutes walk of the flat, which were both outstanding. The flat is clean, spacious and secure, with a fully equipped kitchen, living area, bedroom and dining area. I cannot recommend Marco highly enough.
