It is a really nice place if you arrive in Napoli at daylight or you want to be really close to the station. The neighbourhood is not the prettiest, but its Neapolitan style. You will learn to appreciate it.
Giovanni (or his mother) will give you a warm welcome and they will make sure you can make your own morning coffee.
The bed is not the longest, so if you are above 1.80 you might have some difficulties.
