Zilker, East Austin, Or Domain

Ok guys - 22m. Im currently staying in Austin for a week giving it a feel trying to decide if I would like to move here.

I like Austin as a whole - currently live in Sarasota, FL. Where I currently live is a retirement area, few young people.

I really am trying to figure out the best place to move without being IN downtown area. I like the spontaneous interaction that downtown gives, however would likely be overwhelmed after a while in that setting day to day. I know Austin isn’t necessarily the most walkable city, but is there somewhere that kinda has some of that? I want to be around motivated people/other young professionals. Where should I be shooting to live?
