How did you search for apartments when you are there? I am heading down next week and some folks are mentioning that just driving around looking for rental signs could be the way to go. I haven't had the best of luck with padmapper, craigslist, metro rentals, etc since I have two small dogs.
Which property did you end up going with? Just looked at a map and Westerville seems pretty far out. Did you find it necessary to go that far out for something reasonably priced?
