The concept of "up" requires a gravitational field. Since the ISS in in free-fall conditions -- it's in orbit -- the net gravitational force is zero, so there is no "up" or "down".
That being said, they may state the part of the station closest to Earth is "down"; but there is no real need to do that.

There is really no up or down in space. I guess up would be in the direction of the ceiling.

It's the direction pointed in by the gradient of the local gravitational tensor.

In space there is no up or down.

Whichever direction is above your head at the moment.

In zero gravity there really is no up or down.

There really is no up as there's no gravity to make down.

the direction that points away from earth.
