This thread is pretty dead but I thought I'd give some advice for future folks!
I live in Wichita and have for 10 years, currently finishing my second bachelor's. WSU isn't in a great neighborhood depending on what side of campus you're on — the 17th and Hillside area is pretty sketchy. When I was originally in undergrad I knew someone who was robbed at gunpoint while sitting in their car at night in a campus lot, and I definitely wouldn't be out and about on/near campus after dark if I were alone.
That being said, WSU is a great campus as far as getting from one building to another and I have loved my experience here. There are several affordable apartment complexes near school (I know several people who lived at Willow Creek, Ponderosa, Somerset, and Woodgate, but there are certainly others). I have a car and would recommend it, but I've never used the public transit here so I'm not sure if that's a viable option. I like to go all over the city though so it's easier to have a car for me.
Wichita has made great strides in being more young adult-friendly since I moved here and there are some really cool areas of the city which I love. Kansas is a very red state but Wichita is mostly tolerant and closer to the liberal side of things, which I enjoy.
I would definitely recommend it; the crime stats are scary online but I have lived here for a decade (and alone for the last four years) and haven't had issues. It's a great city to live in if you don't need or want the huge urban metro type of thing but still want to live in a city with plenty of things to do.
