Maria is a lovely host! The apartment is conveniently located close (about 5-8 min walk) to two bus stations and about a 20 min walk to the train station. It is easy from there to get to the main parts of Naples. You have full use of the kitchen, which is nice. Maria is quick to respond to messages.
The apartment does have three Airbnb rooms and only one bathroom so you might have to wait for the bathroom, although this was not much of an issue for us.
Definitely a good option for staying in Naples!
