ASU Poly is really far away from the main city. It's in southeast Mesa, based at Williams Gateway. Rent there is pretty ok, not too high not too low. If you look around, you can find some good cheap places to stay. You will need transportation though, because the public transportation around the airport is pretty sucky.
There's 3 big runways at gateway and some commercial activity. In the last week, I've seen jet trainers, F-16s and Harrier jumpjets, so wake turbulence avoidance is a *****.
I wouldn't recommend ASU to be honest. You have to pay for the flight school in addition to the normal ASU tuition. The cost is too much for what you're getting, but then again, you do get 121 experience with Mesa. I don't remember if it's guaranteed or not, but if it isn't, then it REALLY isn't worth it.

Hope that helped mate... good luck!
