[I'm Italian, writing in english for tourists] The apartment is in a very beautiful ancient building in the old town of Naples. I would absolutely recommend it.
The location is perfect, you are at 5 minutes by feet to visit "Cristo Velato" one of the most beautiful sculptures in the world, as also a museum with a Caravaggio painting and other beautiful churches. For food lovers, the streets are full of street vendors with authentic Neapolitan street food, and the renowned Pizzeria Sorbillo is very near too. The city center is at 30 minutes by feet or less with public transports. The streets are also full of students and people and I never felt worried for security reasons, also in the evening.
The apartment is big, it has 2 large bedrooms very comfortable. Everything was very clean, with a very much appreciated welcome gift made by a selection of different tea too. If needed, it is possible to store food in the fridge and cook it, the kitchen is well equipped for that.
Another bonus is the kindness of the host that was very gentle and attentive in our regards for the check-in.
