This was the only hostel we could book when we arrived in Palermo, and we found out why.
The staff are lovely and really helpful and I feel for them wotking in such a dump, they have tried to make it better but the place is in a terrible state of disrepair and the owners should be ashamed of what they have allowed such a nice old colonial building to become. The roof leaked as though it wasn't there, and we had a big storm while we stayed, the plaster is coming off the walls, the showers are cold most of the time, the private rooms all use the same key so there is no security inside the building, the curtains in the rooms don't fit so anyone passing can look in, there is no noise suppression so any sound carries throughout the building, and the beds are stained and quite unpleasant looking.
I think if you are on your own and a party goer this actually might be a great place due mainly to the staff, but if you aren't stay away.
