Adding one more photo- wondering if I should get a dresser for that space.

I would start with the bedding. Then, those colors can be a jumping off point for art.

Yes, you should have a dresser.

While your room only has three items, play with the layout. Try the bed in a more central position so it has walkspace either side. The Lshaped desk could go on the other side so the lower section runs under the window, and the small drawer set is a bedside for the other side of the bed. See how that makes the room feel. Once you have furniture positioned, think about what the room really needs - soft furnishings, lamp/s and the colors you might like. The furniture, if it is to remain, lends itself of to natural linen tones

Only put a dresser in there if there is no closet in the room. Can you get rid of the desk and center the bed on that wall?

Oh yes, there is a closet in there already. Our family asked for a desk in the guest room so that they can do work when they come visit so we have to leave that in there.

Try putting night stand on other side of bed to create a walkway on that side and break up wooden furniture. Add a good, tall lamp. Replace hard wooden chair with small, upholstered swivel chair. Plenty of good options out there at all price points. Add a small desk lamp. Rooms should have at least 3 sources of light. Once you’re happy with furniture placement, add the largest area rug that will fit in the space. Might only be 4X6, but it will add color and softness. Start with bedding and pull colors from there.

You can find a better desk that is not L-shape. Would open up options for furniture placement.

Yes, please do as Caroline suggested, get that bed out of the corner and put the nightstand to the right of the bed. Beds never look good shoved into a corner, and it makes changing the bedding so difficult. A regular desk would have been better and taken up less space, for sure.

We can't get to your main question, Yanni until you change the layout.

What about switching the bed and desk? Have the desk face the window. Will you bump right into the bed when you walk into the room?

What about putting the bed on the window wall?
