 FAKE: When Kaolla grows up by the power of the red moon, Motoko  explains that Kaolla always slept with her, and never left her side.  This apparently meant the two were roommates. However, Kaolla does  have her own room, and she does sleep in it, as she did in the same  episode in question. And then later in another episode, Kaolla can  be briefly seen sleeping in Motokos room once again.
