Paint your walls and furniture a pale colour to make the room seem larger
Either get bunk beds to take up less room, or loft bed, which don't have a bed underneath so you can have drawers etc there
Have good lighting, so try and avoid blinds or net curtains over a window
Use mirrors, especially on a wall opposite a window
Don't clutter the walls with photo or posters
Paint the ceiling to make the room seem taller
Stripes on the floor or walls make the room look longer (panelled flooring may have the same effect)
I agree it is not ideal, I would try and use underbed storage as much as possible to keep clutter down , bunk beds would be really but if you can't get different furniture how about adding a futon for daytime sitting and night time sleeping.
Firstly, you have to color your room with bright colors because color shows your room as big. After that you get "leather seat sofa bed" for both us. Which you can fold it at morning and there is lots of space become empty & then use them as a Sofa as well as other decorting things in your room.
First, learn where the comma and period are and how to use them. Next, painting and decorating with bright colors are common ways to open spaces up, and bars have been using mirrors forever to make cramped space seem expansive.
