Here are the photos I promised of the soon-to-be-former-guest-room. The twin bed will stay, and we will hang curtains. The fan will go, the lamp is likely to be swapped out with a different one from somewhere else in the house, and the bookcases will move into our bedroom.
The little desk is free to a good home (if you come pick it up). It is from Ikea and is in decent shape.
