The residential units around Olympic MTR station are good and up-to-standard; also, relatively "new" - a friend lives there.
Minor drawback? The two MTR stops not being all that connected to one of the main lines, means she takes taxis or buses during rush hour to the other side of Kowloon, where she works.
So, although Kowloon Bay and Olympic are both in Kowloon, the transport links' such that it may not be as easy(?).
