The hostel is fine. The common areas are comfortable and nice looking. The beds are comfortable too with USB, night lamp and outlet right on the frame.
However the rooms themselves get extremely hot and humid, and I stayed there in the winter! With no ventilation at all and several people sleeping in a tight room, the smell and atmosphere is pretty bad. If you want to crack the window it'll just open for a couple of inches and shut down the AC, ruining any ventilation.
No towels or anything else is provided besides the mattress, one sheet and one pillow.
