I stayed 2 nights in seafront room with a beautiful view of Castel dell'Ovo and Vesuvio.
The room was clean and big enough. Good Service. Breakfast was ok but with a great view.
It has private parking at the basement which is quite pricy (23 per night) but very convenient and secure.
It's about 30 minutes walk to the historical center of Naples, going through via Toledo which is one of the best street for shopping. It is also very close to Chiaia which is a nice neighborhood for shopping and bars.
Not the cheapest nor the most central, but overall worth the money.
