A four-bedroom apartment is a residential unit that features four separate bedrooms, providing ample space for families or groups. Typically, these apartments also include common areas such as a living room, kitchen, and dining area, making it suitable for both relaxation and socializing. These apartments can vary in size and layout, often ranging from 1,200 to 2,500 square feet. They may be found in various types of buildings, including condominiums, townhouses, or high-rises, and are popular in urban areas where space is at a premium.
