Antonio is very reactive and always available to answer to any questions we had (before and during the journey). He is really kind and helpful. When we arrived he gave us a lot of useful tips and information about his city and his island (Procida). His friends, Marco and Enza, are also very nice and available !
The apartment is very well located, in the historical center, between Dante and Toledo stations. You can do a lot of things just by walking, which is very pleasant ! In addition, the apartment is clean and every thing works well.
To conclude, it was a pleasure to stay in Antonio's apartment and discover Naples and around (Pompei, Vesuvio, Procida). I recommend Antonio's place without any doubts !
