I would love to see a picture of this room that has only two walls. Just kidding. I assume the third wall has an entry door and the fourth has a bed against it? Are you wanting to use it as a bedroom, office, workout room, library? Pictures would help for sure.

seriously?

Are you wanting to use the space for something other than a guest room?

Hello, I suggest doing a simple bedroom. Something modern and minimal. You can check my cozy bedrooms idea books.

Hey! Can you please attach a floor plan or some pictures so we could help you.
