Excellent place! Antonio was flexible with the check-in & provided detailed instructions how everything in the apartment works. Also Antonio helped to organize me taxi very early morning to the airport! (Very grateful for that)
This place is truly in the middle of all the action. Even though I was in Naples for just a few days I felt it was easy to walk to all the main places/attractions in the center. You can go out... and yet come back home relatively fast. It feels there that the "city never sleeps" but is enough "behind the corner" to yet feel very private/cozy. I also very much enjoyed the view of the surrounding areas.

Be willing to climb up the steps, as stated also in the description! As a young person I guess you do not mind that. :)
