On-campus housing is required for all freshmen and sophomores. AMR I and II offer the quintessential dorm experience—almost all of these rooms are yellow-walled, two-person squares. The dorms are very social, and people form close friendships. Freshmen often call it "incest" when you hook up with someone in your hall, since you’re going to run into them at breakfast, dinner, and on the way to the bathroom for the rest of the year. Buildings A & B are what most freshmen think they want because they claim to have that same freshman feel except with air conditioning and toilets in their suites. But both of these buildings are tiny compared with the AMRs, which each have hundreds of students. Many of the students in Buildings A & B feel isolated from the bustle of the AMRs. For students who want a quieter freshman living experience, Buildings A & B and Wolman and McCoy are great options. Wolman and McCoy dorms are about five minutes from the freshman dorms. The arrangement is suites with a common room on each floor. A state-of-the-art upperclassman dorm, Charles Commons, is next to Wolman Hall. This dorm has apartment-style suites, each containing four single bedrooms, two bathrooms, and a common kitchen and living room. The dorm also has a library, an exercise room, and game rooms.
On-campus housing isn’t spectacular, but it is acceptable. Charles Commons is the exception—these dorms are exceptional. Since Hopkins has a small campus, all of the exclusively freshman dorms are near one another, and the dorms housing older students are nearby. On-campus housing is expensive, and it requires the purchase of a meal plan. All on-campus housing is monitored by "Hop Cops" (security personnel) and is located near classrooms, dining halls, and other campus buildings.
