We recommend this place because it was clean, you can easily communicate with the host, near the central station (a big bonus for those who are taking the Alibus from/to the airport).
There is just a room (no balcony) in which you have also a small kitchen with a mini fridge (perfect for the morning coffee or some snacks, not for cooking) and a private bathroom in the room. Even though the place is listed as the Entire place, for those who want total privacy or more space, you have to know that there is a shared hallway and more rooms. You won't have the whole place, just your room and your bathroom.
The neighborhood is diverse, to say at least, it won't give you the safest feeling, but we had no problem with the people. Suitable for maximum two people.
Enjoy Napoli!
