Fish's Apartment is on unknown floor of the West Kayne Apartments building.
While only one room of the apartment can be seen, it can be surmised that there are at least three others: bedroom, bathroom, and a kitchen/dining room.
The main room is a visible mess, with posters of airplanes, presumably old war propaganda posters, plastered on the walls. The wallpaper itself is a dull red.
Also in the room is a desk and book shelf covered with Fish's notes and assorted parts.
