I lived at West Bank for 3 years while attending the U (two years in the dorm, and one year at Seven Corners apartments)...it was awesome! I would usually walk to class, but nowadays the connector stops right in front of the Seven Corners area. I paid ~$950-ish for a two bedroom (shared with one roommate - $475 each), but it's been a few years and prices I'm sure have gone up.
In uptown, I could no longer walk to class (obviously), but the express bus has been really nice. When I was an undergrad, I shared an apartment with two roommates for $1335 total ($445 each). Again, I'm sure prices have gone up, but I would think $500-sh for a shared unit should be reasonable. I do not have expertise on 1-bedroom units, but I have seen a lot of them scattered around, and the ones that cost less than $700/mo seem to be a little sketch.
I am going to throw in another piece of advice...if living in a large complex (like Seven Corners Apts.), you will want to get on the waitlist as soon as possible. My roommate and I signed up 5 months in advance of our desired move-in date (which was June). Even at this point, there will be a lot of people on this list in July/August.
Be careful about West Bank....the Seven Corners area (by the law school) is really nice, but the Cedar-Riverside area tends to have a decent amount of crime. Some students still live there, and are fine, but I wouldn't want to. My boyfriend lived in Seward for 2 years and was okay...it is not nearly as nice as Seven Corners or some other areas, but it was a bit cheaper. It was a 40-minute walk to campus for him though (there is one bus that passes though...might take about 20 mins?).
Oh well...hope some of that helps!
