What is the one wall that we cannot see. Is it a full wall? If so that’s where I’d put the bed. I’d create a seating area by the windows....

I would NOT put the bed by the windows. Your window view is probably the nicest feature of the room. You may have to float the bed in the middle of the room. We can't advise you any further until you give us a picture of the wall that is not visible from the pictures that you have provided thus far. We also need measurements and a floor plan. What furniture do you have and what measurements are they?
