The hotel's location is probably the best in town. Close walk to the port (where you can take the ferry/boat to the islands), to the center (is a 15-20 mins walking to the historic center) and restaurants. The neighborhood is safe, close to restaurants where you can enjoy real Napolitan food, and close to the Castell dell'ovo which is also surrounded by nice restaurants (Ciro and La Scialupa, very recommended). The hotel is old but in good condition. Rooms are big enough, and the high celilings make them feel more spacious. Fifth floor has a beautiful balcony, and the best view. Breakfast is very nice.
Definitively will recommend it.
