Marina was an excellent host, very responsive and provided us with everything we needed for our stay. The apartment is a great size for 2-3 people and has plenty of closet/drawer space as well as a big fridge, microwave, and washer. Marina also provided a nice map, train schedule and recommendations on things to do(day trips, definitely recommend Pompeii!) and restaurants.
The only negative was the amount of trash and sketchy people nearby. Because the outdoor market is essentially right out front there are tons of people everywhere leaving all their trash in the streets. At night there is also a group of people that hang around in the alley throughout the evening. The building is safe and secure and about a 40-45 min walk to the water area with restaurants and a great view of the sunset. Also a 5 minute walk to the central train station and 20 minute cab ride from the airport.
