I was there in Dafne's place only for one evening. The description was quite accurate. The apartment is situated in a busy street, with lot of restaurants and shops nearby. As seen in the photos, it is in a narrow bye-lane, and the building is very old, though the apartment is done up reasonably well. All the major places that one might want to see in Naples is a short walk away.
Dafne waited for me when I reached there and explained the place and the surroundings in detail to me. She was quite helpful.
The only minor issue I had was that the shower cubicle was a bit small. So, if you are a tall person, it is not the most comfortable shower that you can have.
