how does the description indicate the setting?

It is Christmas Eve in the Helmer family's apartment, which is furnished “comfortably but not extravagantly.” Nora enters with parcels, leaving a porter at the door with a Christmas tree, which she tells a maid to hide so that her children will not see it. She nibbles on some macaroons she has bought, but she hides them too when her husband, Torvald, comes out of his study.
