Fantastic place! Apartment is like new inside, extremely clean and well appointed. Host gave us good tips on public transportation and places to eat. Well equipped kitchen, air conditioning in both living room / kitchen and bedroom and a great shower in bathroom (best of our Airbnb stays in southern Italy). Its location is a mixed bag, however. The apartment is extremely convenient to train station and taxi stand across the street. 20 euro taxi ride to airport and train will take you to Pompei, Herculaneum, base of Mt Vesuvius and Sorrento. The downside is that the immediate neighborhood is not the most scenic. Typical Naples, as long as you know ahead of time that it's not a stylish area! It is about 15-min walk to the historic center.
We were there three nights, with an early morning flight. We had a full day by train to both Pompei and the Amalfi Coast. Oh, if you plan on doing the Walk of The Gods hike, take the train to Castellamare di Stabia, then the local bus to Bomerano. Train leaves at 6:09am, but you will hit the trail by 8am. Take it all the way down to Positino, then the ferry to Sorrento, then the train back to where you started, Porta Nolana (across from the apartment). Since both stops are end of the train line, you will get a seat!
Overall, fantastic place, and wouldn't hesitate to stay there again on our next trip to the area.
