The airbnb is within walking distance from several points of interest in Napoli and is well equipped for longer stays. It has two bathrooms and a great AC + fan so you can be comfortable in Napoli's summer. The check in experience was simple and overall it is a great apartment to visit the city.
As noted in other comments, the airbnb is located in a street with some bars and it gets really busy at night, specially on weekends. This wasn't a problem to me, but if you want to sleep early and have a quiet evening, make sure to bring some earplugs.
