A studio apartment, also known as a studio flat or an efficiency apartment, is a compact, self-contained living space that combines the living room, bedroom, and kitchenette into a single room. The bathroom is typically the only separate room in a studio apartment.

Studio apartments are popular among young professionals, students, and individuals who want to live in urban areas or prioritize a lower cost of living. While they may not offer the same level of privacy or space as larger apartments, they often come with lower rent and utility costs and are a practical choice for those seeking a simple and efficient living arrangement.
