I would strongly advise against this hostel. We stayed in Causeway Bay at a MUCH better hostel during the first few days of our Hong Kong trip, and it was almost the same price. You can find something a lot nicer in this price range.
-Not too far from Jordan MTR station
-Tiny, dingy room and bathroom
-Dark room with no windows
-Located in a very run-down building
-Very hard to find (no sign outside the building in which it is located)
-Seemed like only one staff member spoke English
-Shaky, dirty elevators in the building
