I never met Giovanni but his mother was very sweet and we had no issues checking in despite our limited Italian skills. The apartment was as described - very clean and comfortable with excellent wifi and air conditioning. We were only in Napoli for one night, so the location - very close to the main train station - was perfect for our needs. Travelers spending more time in Napoli may want to stay in a more picturesque neighborhood but if you're passing through for a day or so, Giovanni's place is highly recommended!
