Well, let's see. We have the ground floor with a living room, kitchen/dining room, bathroom, and my room. Upstairs is my parents' room, my younger sister's room, and a closet. Then there's the basement which has two rooms in and of itself.
I don't know size, but I can give rooms I suppose. Basement is an uninhabitable dungeon. First floor has a living room, dining room and kitchen, and second floor has bathroom and three bedrooms. I have the smallest room because I went for the one with the best view.
