Charlotte Pollard had a bedroom aboard the TARDIS that she used whilst travelling with the Eighth Doctor. It was often in a messy state because of her untidiness. (AUDIO: Absolution [+]Loading...["Absolution (BFM audio story)"])
It featured a drawing room, which Charley used for additional storage. She hid her illustrations of the Eighth Doctor in here, not wishing him to know about her crush.
She once found Audacity Montague here. Audacity was looking for more clothing space. Charley's drawing were uncovered, then the Doctor came in, looking for his gramophone. Audacity respected her wish to keep them secret. (AUDIO: Puccini and the Doctor [+]Loading...["Puccini and the Doctor (audio story)"])
