The writer gives us a general concept that many realtors does not pay attention to, or some realtors may intentionally or carelessly exaggerate their listings. The context also tells how a bedroom is defined. "... it is agreed that bedrooms, living rooms, dens, kitchens, and dining rooms are counted as rooms. However, if the dining “room” is a space in a larger living room with a table chandelier, it may not count as a separate room. Laundry rooms are not considered rooms. Closets, no matter how large, are not rooms, nor are computer nooks. While it is common to see listings for “3-bedrooms, 2-bath homes,” the bathrooms are not included in total room count..." Thanks for the writer's clarification.
