I have seen bedrooms this tiny, and when I was a kid, my grandparents came to live with us for awhile, and I got the smallest room in the house, called the crib-room. It was a little bigger than this, but not much! I love this use of space, and the angle on the bed give it charactwer enough that you don't really mind that it's just bare-bones 2x4's and plywood! Colorful bedding would really define this space!
