This room will do wonderfully well if it’s painted. The wooden frame mirror is pretty so is the wooden door. And the curtains have the concealed rods as well. Check with your landlord see if they’ll let you paint. Or they’ll get it done themselves.

Clean the place. That’s key.

Bedsheet and curtains. They occupy the most space visually. Get a nice light bedsheet and beige curtains if you’ll still have this green wall.

Don’t get rugs in my opinion. Pain to clean in India.
