The place was AMAZING and resulted for us to have a great experience in Napoli.
Apartment is modern with lots of nice furnitures, mattress and beds are very comfortable. Kitchen is equipped with all you need (microwave, washing machine, dish washer, and etc) there are two big TV, and even one Apple Mac PC connected to Net with printer to use. Balcony is fabulous with a unbelievable view that I could stay there for hours and watch ferries moving along the harbor of Napoli next to the Castel.
Also place is located in the rich area, completely safe (We even went to seaside every night and came back 3a.m). There are about 300stairs that goes from doorfront to the seaside.
I EXTREMELY SUGGEST THIS PLACE.
