I split my time between Zhuhai(China) & GP since March with an occasional trip back to San Franscisco. I don't know much about HK even though I grew up there. I've been gone for a long time. I love living in GP. GP, of course, is brand new and its view(right on water) is one of the best in HK. The facility should be great & is scheduled to open this month. In addition the neighborhood has tons of open space, many parks and hundreds(almost) of restaurants. All these packed in an extremely convenient location. Go for it.
Meantime, desperately looking for tennis partners.
