I would put the bed against the wall across from the bathroom door. It will be under the windows, but should give you the most space. Enjoy setting up your space. :)

My room is pretty small and it's spaced awkwardly I currently have little furniture, I have a small desk a large book case a guitar on its guitar stand and a twin day bed that I'm replacing with a normal queen bed ( i don't have much furniture so I think I should be fine) how should I organize it ??

Ps some things are exaggerated the bathroom door is the same size as the entrance door.

Thank you so much :)
