Bought a Couch!

I bought a couch off of kijiji for $70. Here are the pictures from the poster's ad. Please ignore the poor styling. I'm planning a much prettier look for this piece:

I love that it's white for all of the colorful accent pillows I'm planning to add. It's also on the smaller side (which will be perfect for my new rental space in the fall). The seller was asking $100 originally but because she really wanted it gone to make room for new furniture, she let it go for 70. 
The only problem is the cushion covers are DIRTY y'all...but I think a good bleaching and scrub will have them looking good as new! Do you have any tips for washing cushion covers from IKEA?
I'm also thinking about painting the wooden frame black..any thoughts?
