The place he goes to is just off La Salle Road in Kowloon Tong as we can see from the following screencaps. Check out the plane doing its turn into Kai Tak in the top picture.
Sadly, he doesn't go into the rather elegant looking place on the opposite side of the road, but instead pulls in to Dumbarton Road (the west part on the west side of Kowloon Tsai Park). The plot he goes into has actually been completely rebuilt - a very common occurrence in Kowloon Tong because the plots of land are relatively huge - so we will have to make do with a picture of a much more modern building that now sits there called La Salle Court (the shiny one left of centre)
Far more interesting, in my humble opinion, is the building we see in the top two frames. By some sort of bizarre luck, this place is still around and so are its nice elegant iron gates.
It's called Hyde Park Villa and is probably an original building the 1950's (occupation date says 1957). It's very similar to the style of property we also can see over at nearby Yau Yat Tsuen which was developed in the 1950's. Very stylish I think, and nice to see that it hasn't changed for the past 25 years or so.
