I lived in Iowa City for several years while my kids were young. It is an amazing city. Everyone is lovely, the restaurants are great, home of an active local grocer, tons of activities by the university, great schools, low CoL, completely walkable, and nothing was ever more than 5 minutes away (yes, when we moved, I had to reorient myself on what "far away" was). I think my kids were lucky to grow up there!
