We had a lot of fun here. The staff were very helpful with directions and participating in the fun. The room was not one of the best we've stayed in and had one of the worst bathrooms i've used - no toilet seat. We later found out this was an exception rather than the rule.
The hostel had good cooking facilities, booze on supply and a decent common area although only one computer. We stayed here for one night only because we wanted to see Pompeii but if i did it again i would just skip Naples altogether, it's not the nicest city. Great pizza however.
If you do stay I think there are a couple around but going by what we had experienced so far this wasn't bad for the price. Just wear thongs in the shower.More
