Yup. I lived in on-campus housing my first year, and then I moved to off-campus housing to save some cash, but it was still walking distance to the campus (like 2 blocks). 90% of my classes were in the same chunk of land, with each building being dedicated to some specific part of the university (e.g. the math building, humanities building, music building, etc). There were a couple of buildings separate from that chunk of land, but they were also within a few blocks from the main campus.

You can get by w/o a car and can do all the shopping you need right on campus (ours had a small grocery store), and there were even fast food restaurants inside the student center building (or you can go to the cafeteria, but that was at the edge of campus), so you could eat lunch right there w/o having to return to your apartment. Some days I would go to campus at 8AM and get home at 10PM when most buildings closed for the day. Our library was right in the middle of campus, so I’d frequently go there to study between classes, because I always seemed to have an hour here or there in my schedule.
