the apartment is fantastic with the see view. location is quiet and nice, different than the "typical" Naples. you can definitely have a nice stay. Paolo's recommendation to the restaurant was also really good, we had a very good dinner enjoying the view to the whole port.
One thing to point out: it's a bed&breakfast, so no real kitchen access. for those who like to cook your own meals maybe not the right thing. otherwise it's worth every penny you spend.
