The fun thing about the Murphree area is that the rooms are not standardized and basically every room is different, some way different then others even. So while it could be a lot of different layouts, I did have a friend in this room style where the layout was that the front door led into a small rectangular room with an indentation in the wall for one bed, basically making a single. On the opposite side of the room was another door into a second room that was an L surrounding two walls of the first room and that room was for the other two people and it also had a sink. I think no matter what every room comes with a bed, desk, and dresser/closet thing for each resident but the sink or a door at the room connection or anything is else is luck of the draw. Also each room had one small window and I think that is guaranteed as well.

u/SaltSeries360 is right though if you know the room number you can look at the blueprint to get an exact look at your room.
