The stay in Aldo's place is way better than how we expected. The size of the room is big enough to put our luggage, and the toilet is quite spacious, clean, and neat. Various from the typical Neapolitan noisy streets, it was quiet during the night.
Especially the check-in time usually starts from 2 but they let us check-in around 13:30 since I've arrived earlier. I would definitely recommend this place and stay here again!
