My partner and I had a great stay at Sergio's home! He was very available and communicative, and very accommodating and helpful. The apartment was spacious and comfortable with all the amenities we needed for our short stay in Naples. It was a great home base for our visit to Pompeii. It's just a short walk to the first Circumvesuviana train stop at Porta Nolana, so it's very convenient and you're much more likely to get a seat for the 30 minute train ride than from Garibaldi. And Sergio gave us great suggestions for food and what to do while we were in town!
