I don't know, I've heard not so good things about Azure and the apartmentratings.com reviews seem to back it up.

I don't really know what else is in Marion, but if you don't mind an extra 10-15 minutes added to your commute, I know a couple co-workers that live or have lived at The Point off 42nd Street NE in Cedar Rapids and they've said good things about it. They're reasonably priced and have been recently remodeled. There's also another apartment complex off Boyson Rd. in Hiawatha that seems pretty decent.
Edit: I did a quick search, and here are some better ranked ones that came up for Marion that you might want to check out at that website: Wexford Apartments, Chapel Ridge Apartments
