IMO you cnnot put curtains on that whole wall you have a rd on the left so the door IMO needs a blind only. it could be a roman blind in a fabric to mtch the rapes on the window if you want drapes there . I hve no idea of your style of the space so pretty hard to help much more. It looks like the door swings in too so tht makes mounting a blind a bit tricky so the blind will need to be mounted high enogh to allow the door to open Then just hang the drapes at that same height or just use roman blinds for both .

I would do a made to order blind (inside mount) top down/bottom up.

for privacy and/or light control. Such a small space, blinds would be less bulk than curtains, make the room more functional and less cluttered. many color/fabric options Blinds.com or other blind sources

Can you show me a picture because I cannot open the link?

Assuming you want to cover the door and window for privacy and light control? If so, then purchasing a blind for the door and window would work best - a top down model would enable you to let light in and maintain some privacy - there are lots of options

There are no rules, as window configurations and privacy really dictate; I think this application would be a good choice.

Perhaps use solar window film on door and have bamboo blinds on window that compliment with the floor.
