Many may have different opinions on it, and/or other sites to share. One decent hostel review site I found is:

http://www.hostelz.com/


Now, for me, I not only have to look at how many or few reviews, or how many negative or positive ones. At hostelz.com, reading through WHY the person did or did not like the hostel will tell you a lot about what a particular hostel is like.
