We enjoyed staying at Lina's apartment, and everything went great: perfect location, amazing terrace view, superkind host. Two things were slightly different than expected: 1) the terrace shown in most of the pictures is only accessible during breakfast, and is the terrace of Lina's apartment (NOT of the property rented); 2) The listing is a private bedroom with bathroom and independent entrance rather than an entire property: there is just an internal door (locked) separating the room from Lina's apartment.
Despite these two points, our stay at Lina's was great, and we think the apartment is a very good solution for a couple of days stay in Naples.
