Where does Sunny live in the novel, What We Were Promised?

Sunny lives in the outskirts of Shanghai in the Hongkou District in a group living facility. She lives in a room with five other roommates, each with their own bunkbed, and shared bathrooms that smell of boiled cabbage, urine, and copper. The contrast between the Lanson Suites and Sunny’s apartment is striking and symbolizes the discrepancy between the different classes.
