If you can't clean up the painted edge, you could always add a 1x3 piece of wood as molding. You can even carry it up to the ceiling to frame that wallpaper. I don't see that paint color in the wallpaper, or maybe it's a lighter version of the flower centers. Maybe stencil on a design using the darker color, or another color from the wallpaper to help tie it together. Then narrow floating shelves or vertical frames or something in the painted areas it you feel you need it. Maybe turn the bed around so the wallpaper is the headboard.

I've had pleated blinds, metal horizontal blinds, vertical blinds, and wood blinds. Even though there are pretty pictures of blinds, blinds are not my favorite, especially vertical blinds. Blinds are impersonal, not cozy imho, and pleated blinds are very difficult to clean. They attract dust and pet hair, I think, by static, and vacuuming does not get it all. Horizontal blinds, if cracked open for some light, leave a striped pattern on the window which I don't like, are a pain to dust, and are pretty much "all or nothing", and you can't leave blinds open at night if you value privacy. Vertical blinds remind me of corporate conference rooms. Sorry, I hope I'm not offending anyone. Curtains on the other hand, can be soft and flowy, let light in without compromising privacy. You can wash them or dry clean them. You don't have to open and close every single day to adjust for light/privacy conditions. Curtains are easy to change out, and you don't need a custom size if your windows are not standard sized. I haven't had the pleasure of roman shades yet, that's my next new thing to try. More than you probably wanted,mikneleh... LOL! Have fun with your decision.

Nadia, You need to provide some more snaps showing the entire room, including the location of the beam, its height & clear height of the slab etc. One idea could be to extend the width of the beam by just about 25 mm with gypsum board on either sides, at the bottom level, with a right angular vertical of 25 mm as well & provide LED lighting strip for indirect lighting...
