HK offers one of the widest range of possible accommodation in the world (for such a tiny place).
You want to live in the heart of the city - you can
You want to live in the mountain - you can
You want to live by the sea - you can
Next to a Park - you can
On top of an MTR Station - you can
High Rise - you can
Houses - you can
Cheap - you can
Expensive - you can
and what is great is that all this is within an hour or so of anywhere you want to go.
NOW, when people come on here asking specific question about living in Sheung Wan or Mid Levels, I advise them as best as I can on Mid Levels and Sheung Wan - Perhaps I add a line or two about other options such as WanChai or CWB
But when their requirement is : I wanna be in the middle of the city, we are young, want to socialize and go out...I do not mention the NT (where I live) because let's face it, it's not the same feeling (heat of the city, socializing..). I chose the NT because I like it, I'm older, I've been here longer time, I have experienced the crowds, partying..it's cheaper, it's bigger...but that's not what the OP is asking.
I am all for telling people that they should sometimes, consider NT or Kowloon - especially when they come with queries such as we have 15K to live and want 3 bedrooms...yeah well tough luck this ain't gonna work on HK island (debatable in some areas I know) but in this case I think here clearly the OP isn't much interested in NT (her bf/husband hates Tung Chung...says it all I think) so what's the point?
