It's a good one when you just need a bed (as I do). However, there is also a fully stocked kitchen and two bathrooms. Place is very clean. Giovanni is a gracious host; we arrived very late due to reasons of stupidity - we got lost in the Napoli harbor :D - and he came to the place especially for us quite late at night. Thanks for that!
However, there are two things to know before booking:
1. It's not the whole apartment for you alone. It's implied in the profile but let's put in in plain words: are three rooms, all of which are airbnb'd. So in our case, we were 7 people. Can get a little awkward if you don't know each other. There are two bathrooms though.
2. It's definitely *not* quiet. Room windows look down on a busy street right next to the harbor (no biggie for me). BUT the locals seem to communicate by honking alone. On weekdays, it starts at around 6 and won't really stop. Sometimes the honking cascades into big symphony concerts. This is a citywide thing though. Napoli is not a quiet city, not is it one where traffic rules are more than friendly recommendations.
Anyway, if you are like me and you just need a bed to rest your weary head on after a day of exploration, it's fine for a good price.
