My stay at Generator was my first experience at a Hostel - and it was great! I was in a bunk room with 5 other people.
Bed, sheets and pillow were fine, and I liked the large (lockable) storage box underneath the bed. The wifi was decent also.
The bathrooms were relatively (surprisingly) clean and towel hire was €5.
The best part was the rooftop bar. Drinks were very expensive, but it was a great place to chill, book the next part of your holiday or meet people!!
