Yep! Since the same side of the ISS is always facing down towards the earth, every time it orbits once around the Earth, it rotates once around its axis.
Actually, every time an ocean liner travels around the Earth once, it has also rotated around it's port-sternstern starboard axis!. A better example would be a plane, it slowly rotates around the axis through it's wings as it travels around the Earth.
There are some nice images in some of these Quora answers.
Actually I will repost one of them here. The ISS is traveling in the direction of it's own $X_{LVLH}$ axis, and so it rotates about it's $Y_{LVLH}$ axis once per orbit. LVLH stands for "Local Vertical, Local Horizontal."
