Well if this isn't a coincidence I don't know what is.
Just to my left here I noticed I still have the receipt from that stay in the hostel two years ago.
No. 40 Nathan Road
ChungKing Mansions
Block A, 3/F
Kowloon, Hong Kong.
Not sure where along the road you were but that place was 40. Thanks for posting the pic, now I'm going to be rooting through pictures of that trip reminiscing instead of going to bed!
