Hi Margaret,
I live in Chung Hom Kok and find it very convenient - it's only 15 mins walk down the hill to Stanley (or a quick hop on the bus), plus close to Chung Hom Kok beach & playground which is very quiet as the tourists don't know where it is! Only down side is that there's a number of steps to reach the beach, so it's not very stroller friendly (we use a baby carrier when we go there instead).
Most of the Stanley buses go through CHK, so I use the buses all the time to easily get into Central/Causeway Bay.
Send me a message if you have any more questions, or would like to meet up - I have a 9 month old and am not working.
Anna
