[Hmmm... Layton looks at Phoenix thoughtfully for a moment, and then a smile grows on his face ohhh so slowly.]

I live on the fourth or fifth floor of a certain building. The walk to school is a rather long one, but when I'm running later than usual, I can still make it on time without running at all. It's a lucky thing, too, because on those mornings, I always find myself horsing around.

As for the room number? 23.
