If you're looking for a cost-affordable AirBnB away from the busy, high-traffic downtown of Austin, I would highly suggest Marie's. It's located in a quiet neighborhood. You get a private bedroom and a shared bathroom. It's about a 5-10 minute walk to the nearest bus stop (Take the #383 south if you want to make your way into Austin). Any other special requests you may have, Marie is more than accommodating. Definitely worth the price.
