Only partially documented. But there's a window here, facing our neighbors to the East.
Just today I decided to explore this little room more fully. Most of the space is taken up by the air conditioner and its flexible conduit, but there's space for a few things like this wrapped package. It's fairly light, but it's got enough heft that you know something's in there.

A couple of months ago I accidentally locked my then-girlfriend Shannon's cat Monkey in this room for about 18 hours, after I took these pictures. Poor kitty - he's been locked in all sorts of confined places, including the cedar closet (5 hrs), a small blanket closet next to the bed (14 hrs), as well as most of the other closets (> 1hr) in the house, but this was the longest. We couldn't hear him meowing because of a very loud fan, but Shannon noted Monkey's absence, deduced his location, and freed him. I got to give him a bath as penance, but it wasn't too bad, and he was very fluffy by the end of the day.
