Single Apartments are either setup for double or single occupancy. This means there is either two beds, two desk, two wardrobes etc, or only one of each. This depends upon whether the room is setup to accommodate individuals needing ADA accessibility.
Single apartment rates are the same regardless of how they are setup.
Shared apartments are set up to accommodate two residents. Each resident has their own bed, desk, wardrobe, desk chair, and desk lamp. Residents are expected to share the use of the kitchen access & supplies, pantry, kitchen table, bathroom access, and closet.
