- basement windows at chin level
- Obamas' on first main floor
- Obamas' windows looked out over street

- main floor had been divided into four studio apartments about 500 square feet each
- Obamas lived in apartments (plural) above garage

Trying to figure out where within this house they lived is an exercise in futility imo because the house card and the house photo that were used don't illustrate any residence that ever existed on that block. If you want to get into why, you better have two or three hours to devote to the subject and REALLY want to know.
