I'm sure this place is like the plethora of other hostel / guesthouses in the Chungking Mansions, small. We stayed 4 nights and really only slept here. For that it served it's purpose. You don't stay here to have a relaxing holiday resting up and relaxing in comfort, you cannot do that in these tiny rooms. Sheets and towels were clean, if a about old. If after somewhere to just rest your head at night at a cheap price, in the centre of all the action on Nathan Rd then this place will fits the bill.
You'll have to be patient waiting for lifts and be okay to asked to buy 'butter chicken' from the multiple Indian food sellers on ground floor (don't buy tough, infamously makes people sick, we are advised). One bonus is you have the best currency exchange rates in town (as advised by a friend who is a local) at your door step at the many currency exchange places on the ground floor entrance level.
