The pic comes from Eternal 1966e's collection on Flickr where it is dated 1930's.
Stokes Bungalow is the dark building at the bottom of the photo with 274 The Peak (later 71 The Peak) the light coloured building above it. Ap Lei Chau is the large island on the right.
The matsheds in the upper left corner are on the site of Gough Hill Quarters which were built between 1923 and 1925, from which it would be possible to conclude that the pic was probably taken at that time. However, I think The Holy Spirit Seminary can be seen down in Aberdeen (if not The Holy Spirit Seminary then what is that building?) which wasn't built until 1931 so I'm confused about the date.
