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.

Vitrified Wooden Tiles or Planks will be best suitable for your Room as it has greater strength. It available in 200x600 mm. and 600x1200 mm. Nowadays the wooden planks tiles are very popular due to their aesthetic feel and unique designs concept. An infinite number of tile possibilities can be achieved with the help of inject technology. Realistic wood patterns are also available.

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.

Alosha, It would require more information from your side. Is it a wall that is panelled with plywood or just the shutters of a wardrobe. Are there any joints of plywood visible. If feasible share a pic please. Thanks,
