ineffable, intrinsic, private.  Those 3 sound accurate to me.

Is this the 4th?  - to directly experience a quale in consciousness is
to know all there is to know about that quale?

I do not see the fourth property of qualia as Dennett enumerated above. 
My understanding of consiousness is a cognitive process with varying 
degrees of behavioral responses. All I know is that in general 
anesthesia there are four levels of consciousness. But the article 
failed to mention the fourth property of qualia which is reversibility. 
When a patient recovers from anesthesia the process is reversed from 
the fourth level of unconscious state as in deep sleep to complete 
recovery, the first level or complete awareness/awake.

There are many properties of what the brain can do and 
qualia/consciousness is just one of them. Scientists call this property 
of the brain as cognition.
