The apartment is very conveniently located at only 350 metre from Napoli Stazione Centrale railway station, Garibaldi Metro station & the Alibus stop for the airport (5 euro & 25 mins one way). It is also located just off the the main Corso Umberto street if your interest is in conventional Italian cafes, shops & restaurants. There is a wide choice of food & clothing market stalls nearby too if you want to experience Napoli like a local.
The hosts were very prompt with their correspondence. They arranged an early check-in for me and even enquired during my 4-night stay if they could they provide any further assistance.
The street where the apartment is located and the nearby area look run-down, but so does a lot of Naples once you move away from the main streets. It was quite safe here. However as with many other cities, you need to take care of your possessions when in crowded railway stations and metros. Most places of interest are walkable from the apartment.
