The location of this place is central and in a good neighborhood, right near a metro station under construction and south of the old town.
The room is one floor up from the basement, with an elevator available. It was very clean, including its adjacent bathroom with large shower stall. There’s even a cleaning lady, making the bed every day, except Sundays. Both hosts greeted us upon arrival, and shortly explained the place, after that we were communicating in a WhatsApp group.
Their restaurant recommendation turned out to be perfect (Trattoria Medina, and Dattino across the street, ask for Angelo). The Italian breakfast is pre-prepared/packaged, and offers enough goodies for those who wish to eat in. The coffee/espresso machine was furnished with plenty of coffee pads, and proved to be a welcome pick-up after long walks.
All in all a place we would go back, and explore Napoli even further.
One word of advice for travelers with suitcases on wheels: Sidewalks in Napoli are not very suitable for rolling a suitcase easily… There is a taxi stand on the main street about 100 m from the Airbnb.
