Size
Both studios and efficiencies are typically small apartments meant for occupancy by a single person. They are designed to be basic and inexpensive. For many renters and buyers, these apartments are an affordable way to get into a convenient or upscale location.
Efficiencies
Efficiency apartments, also called bachelor apartments, are always small and feature a combined living and sleeping space. Most efficiency apartments are one room with a separate bathroom. Efficiencies have a kitchenette area attached to the living area. A wall of appliances and counter space is a common setup. The appliances are often smaller than usual, such as a half fridge, a one or two burner stove and a small sink with a small counter area and are more for heating food than cooking full meals.
Studios
Studio apartments are not always small, but are always one room that combines the living and sleeping spaces. Some studios may have an alcove area for sleeping or a loft area that is open to the main room. They feature a separate bath and kitchen with full size appliances.
