Help Me!

By popular demand, I will be reinstating my "Help Me page for all those locations that have just been eluding me. Any suggestions welcome as often even a wrong guess can trigger a new train of thought and potential lead. Thanks in advance.

I'm currently scratching my head at the following property used as Han's house in Hong Kong Godfather. Exhausted all my usual lines of enquiry. Feel free to offer suggestions. It's a rather squat property at the front so, given the surrounding terrain, I suspect it is terraced at the back. 

The restaurant scene when the newcomer tries to give Mr Han a present and is rebuffed and an argument ensues.
