Nope, that makes it sound like you've been thinking about it ever since. You have, but no need to let her know that. You want her to think it's no big deal.
I'd set up a situation where you're doing something with her that will lead to either of your apartments. Invite her over on some pretext. Hang out. Maybe lay on the floor and watch a video together (chick flicks work well for this). When the movie is over, Turn down the lights. Light candles. put on music. get close and talk. Get closer, and make your move.
Good luck.
