I need some help treating a very peculiar room!

[Turtlesofthought]

So I live in Hoboken, NJ which is short on parking and even shorter on large open apartments.
I've turned a second bedroom into my studio room for lack of other space, but I really need some help deciding the best way to treat it.
It's a small room and I don't have significant issues with ring or echos, but my bass response is obviously all over the place.

Here's the kicker...
About 60-62% of the room is at a ceiling height of 5'7" due to a lofted full size bed enclosure.
The remaining portion has a full 9 ft ceiling, but due to the unique challenges with space, I'm not sure how to go about high efficiency treating of the room.
Attached is a drawing with dimensions, and I'm not opposed to doing anything except cutting out the bed (which i totally would if I could).

Thank you in advance for your help, the GS community is unbelievable and I'm sure the different opinions on how to deal with my split will start a nice discussion.

You'll treat that room the same as any other - as much corner bass trapping as possible, plus absorption at the side-wall and ceiling reflection points.

So nothing weird happens due to the jutting out of that ledge?
I'll get right on the trapping the corners.
For clarity, you are suggesting treating the wall opposite the window and the ceiling above the open space?


EDIT:Ethan, I've seen your numerous posts on the topic and I was hoping you'd answer!

Look, it's a tiny cube shaped room. Yes, it has lots of issues. What I suggested is what's needed to reduce the problems as much as physically possible. You'll also want to treat the wall behind you since it's so close.
