Building W20: Stratton Student Center

Centrally located, open twenty-four hours per day and seven days per week, the Stratton Student Center offers places to gather, study, dine, do errands, and relax. The first floor serves as a campus commons where students congregate and meet. With more than forty student offices and lounges, seven dining venues, a reading room with group study spaces, the campus’ largest Athena Cluster, an art gallery, an MIT Coop bookstore, a dry cleaner, two hairdressers, an optical shop, two banks, a supermarket, caffeine outlets, a post office, and several important Division of Student Life offices, there truly is something for everyone at the Student Center!
