How is Mrs. Harris' London apartment described in the novel, Mrs. Harris Goes to Paris?

Mrs. Harris’s London apartment is a small basement flat where she lives by herself. It is described as dimly lit and decorated with modest furnishings that reflect Mrs. Harris’s low socioeconomic standing. While her accommodations are unpresuming, Mrs. Harris uses flowers to bring beauty into her home. The author depicts the apartment as provincial and cozy to symbolize Mrs. Harris’s unmaterialistic nature.
