Just beside No. 1 Broadwood Road, there is a steep stairway leading to an alley with no name. At the far end of the alley, you can see an old building belonging to St. Paul's Primary Catholic School (聖保祿天主教小學). On the right and circled in yellow, you can see the 4th floor of a 6-storey building. That's No. 87 Wong Nai Chung Road. I was living there for about 18 years during my childhood and adolescence, overseeing Broadwood Terrace every day from the window.
Incidentally, the postal address is 4th Floor, but it is actually the 5th floor (in Chinese address) as the British way is to start from the Ground Floor.
