Cara - hey, if you know someone with a 100K+ place, can you get me a playdate? Sheeeeesh, cannot imagine that place!!! WOW!
Re: Lai Chi Kok - my friends live near LCK station (Banyan Garden - very nice apartments, normal HK size, FAB clubhouse), but I have to say I hate going there because LCK station has NO escalator or elevator and you have to walk up stairs, which is an absolute nightmare with the stroller and waiting around for no one to offer help. They're building a covered walkway to the apt complexes (to be completed this summer but I would doubt it) and I would PRAY that they will include an elevator from LCK station in the plans, but...who knows. Just FYI...
Oh, also Kowloon Station has lots of nice apartments there(on top of Elements mall), but I think some are a bit pricey, thought you still might be able to meet your 25K budget.
