The appartment was clean, and nice just as in the pictures. For this price you almost can not complain, she even had some little breakfast prepared and Alessia as a host was very nice. I would like to mention some things since you can't find this in the description:
1) You have to sign a contract when using an airbnb in Napels which is apparently the normal course of business, including copies of you passport.
2) The appartment is near the airport, which is nice but is also in the extension of the runway where aircrafts take-off. This is very loud. (In the Netherlands they wouldn't let you build houses in these places due to noise disturbance).
To conclude: You can not expect much for this price but I wouldn't booked it if I knew that the appartment is in the extension of the runway. If you do not mind this then this is a great place to stay.
