The Walkers are an African-American family from New York City that live in Stacey McGill's old apartment building in Apartment 18E.
Mr. Walker and Gabrielle Walker are artists and they have two young children: a son Henry Walker and Grace Walker. They always leave out paper plates & plastic utensils when a baby-sitter is going to feed the children.
The Walkers' apartment is described as being filled with sculptures, wall hangings and modern artwork.
The apartment rooms are the same arrangement as Stacey's old apartment, but their dining room has been changed into an studio; they are no curtains or windows on the windows. Mr. Walker's easel and chair are on the left side of the studio while Mrs. Walker's slanted desk is by the window on the right.
