I already posted about my freshman year but I guess I'll give my whole college living experience.
Freshman year: Friley - loved it, doing a year in the dorms is essential. It's how I made friends that first year that lasted through college and it's a good transition from living with parents to living on your own with really only half the responsibilities.
Sophomore year: Apartments in West Ames - Worst decision I ever made and I wouldn't recommend to anyone. Bus routes were limited so I skipped a fair share of classes because I wasn't gonna walk 2.5 miles if I missed a bus. My grades slipped because of this. I know that comes down to a personal responsibility/motivation factor but living this far off campus made my motivation a lot lower. I was limited from the social aspect of campus and felt secluded.
Junior/Senior Year: Moved into a house just west of state gym with some friends - This was the best decision ever. It was the stepping stone to real life and living in a place that I had full responsibilities for (other than maintenance expenses). I made some of the best memories of my life in this house. It was also a close walk to the engineering side of campus, state gym and the bars (which was very important). It was nice to have a yard and a fire pit for parties/bonfires/cookouts which was missing at the apartment. The only downside to this house is I'm sure I have permanent lung damage from the mold in the basement but oh well.
Super Senior Semester: Moved to an apartment on the east side of town near Duff - This was fine. It was a nice apartment with great amenities, but I had gotten used to living in a house. It was a great place to live during football season because it was a short walk to the stadium. At this point I had saved enough money from internships that I was comfortable wasting a little money to drive and park on campus for the few classes I had. If driving isn't an option I wouldn't recommend living too far off campus.
