I really recommend Raffaele's apartment! It is very cosy, comfortable for 2-3 person. Small kitchen with facilities, very clean bathroom. It's located on side street, close to the one of main street, so it's quiet place, but you have all night life (famous pizzeries, cafeteries) within reach a short walk. You have also the best places to see in Napoli in short distance. Great place to stay for visiting town. Reccomend!
