We stayed 5 days in Napoli and we really enjoyed Lucia's appartment. It is very central (close from everything: historical city center, port with the boats to the ilands and 15 min walking from the train station Garibaldi).
The terrasse is really nice (quite big and not too noisy), everything was ok. The room is cute, clean, calm, with conditionned air which is appreciable!
We didn't met Lucia who was on holidays, but her parents welcomed us very kindly.
I would recommand this place to everyone who wantz to spend some days in Napoli!
