Wonderful hosts who make a great effort to make sure you have what you need. They gave excellent recommendations for food and were responsive to all communications. They helped us get a taxi for our morning flight, and I can't ask for anything more. The apartment is huge, and, as noted in previous reviews and the listing, there are a good amount of stairs to climb (second floor is what we would call third floor in the US)- par for the course as far as our other Italy experiences went.
Even though this place is only a 10 min walk from the train station, I highly recommend getting a cab, especially if you are arriving at night. Naples was the roughest city we visited on our two week trip, and I felt like I was on high alert just arriving to the city and trying to navigate with my bags. Once we were checked in, we felt very comfortable walking the city. The location of the apartment is convenient, and we are happy with our choice.
