constant screaming, dragging of furniture, stomping, kids playing in the hallways instead of the ample playgrounds outside, loud music, loud TV etc is not acceptable. even normal conversations can be heard thru the walls in the GC. it's like your life has a constant unwanted soundtrack. plus Sino is ever-renovating the units, and the mgt is very hostile once you start complaining - the person who leased my apartment to me now won't even say hi when we pass each other. nice going.
for the money you can get a huge range of places in HK, most much more central than So Kwun Wat/GC. Don't even bother with this place, it's just another big obnoxious tenement, no matter how flowery the promises.
And for the record HK isn't noisy by some mysterious force of nature, bad neighbors choose to be like that, just as quiet people choose their way of life.
