Where to run ethernet cable in a 3 storey house?

[imwired]

Here's a bit of background:

I've got 2 routers: DLINK 655 and 625
I plan to use the 655 as the main router on the 2nd floor (top) of the house and the 625 is going to be used as an AP in the basement.

I want to run a wire from the router to the AP using a CAT5e cable.

Which of the two would be better? or is there another option?

Any thoughts/suggestions?

Thanks
