All in all we had a pleasant stay at Francesco's place. We booked the place on short notice and, having visited Naples before, picked it due to its central (albeit touristy) location.
Pros:
* Good central location
* Clean house with a nice modern look and A/C in good condition
* Francesco is polite and tried his best to accommodate us
* No problems with the neighbors everyone was friendly
Cons:
* When we arrived we found a small pool inside the apartment which was covered that was taking a considerable part of the space (e.g. the open wardrobe was not accessible). There was a chlorine smell throughout the apartment owing to the chlorinated water in the pool. This was exacerbated by the fact that the apartment has poor airflow as it has no windows. Although Francesco offered us to switch apartments the other apartment could not easily accommodate the three of us and after some efforts we found the smell to be tolerable by operating the ventilation of the bathroom and keeping the apartment door open for some time. It was hardly ideal though.
* Some minor things in the apartment need to be improved; defrosting the fridge (which also produced water leaks), replacing some bathroom accessories, ensuring that whoever is taking a shower is not visible from the WC, etc.
* Communication mostly done through airbnb's built-in translation tools
