The apartment is actually much bigger than it looks on the photos. Perfect location for sightseeing on foot, the old town is 5 min away. Good place to stay also if you're planning to take a train to Sorrento or Pompeii, the main train station is 15 min by metro from Dante metro station which is 5 min walk from the apartment.
Marina is also a wonderful host. There was a notebook in the apartment with recommended restaurants, train times to Pompeii, useful tips, etc. She also helped us organise the cab to the airport and was very quick to respond to any queries we had. Overall wonderful stay and would definitely recommend staying here.
