Pro: The staff was nice and kind, speak english very well. They answersed fast to all my questions adressed on booking messages. They gave me good directions to the places I had to go. They have a nice reception where you can stay and make new friends. The room was cleaned daily. The toilets were clean. Inside is a safe place in an unsafe area, if you feel unsafe on the street they are there to help. They have free tea and coffee full time, not only at breakfast. The breakfast was good, diverse and tasty.
Con: The hostel is located in red light district which can be unsafe if you travel alone, but from my experience (travelled alone) the biggest problem is your misunderstanding about what red light district means. It is more in your had than on the street, the Police is there all day. A big visible lighted loggo on the building would be great. I arrived there by night and I barely found the place, and I felt uncomfortable due to the area. On the door would be great if you have a message with "Ring ->"
