Her reaction was due to a sudden ego boost but that doesn't necessarily mean she likes the guy.

No luck, the opportunity hasn't made itself manifest. Which is fine. Frankly I find that talking to women just isn't worth the risk of embarassing myself.
It's not really unusual for neighbors in the same building to introduce themselves to other neighbors. If you did get up early and introduce yourself on the way out, there would really be nothing unusual about that, and if she acts like you are a creep in response to a socially acceptable introduction, then she is the problem, and you should have no cause for embarrassment.
You could say something like "Hello! I'm Brian. I live on the (whatever floor). I see you down here a lot and I just wanted to introduce myself."
If she responds poorly then you know she has problems, but chances are, she will respond in a socially acceptable manner.
