I will say that commuting on the CTA is neither relaxing, or a good place to unwind. I'm not saying that it will be terrible, but the trains, especially the red line, you will almost never get a seat, and there will always be a ton of people on the trains, normally all up in your personal space.
I know you said you are moving with your fiancee, so that will weigh on your decision, but I would echo Orchidmph, and say that I would live as close to campus as utterly possible. I don't know who you've got your information from, but I have spent a decent amount of time in University Village, and know tons of med students and residents that lived there, and I don't think the area is loud or rowdy, especially near the med center. Maybe closer to the main campus, but even that I don't think it's loud or rowdy at all.
