Lakeview, just north of Lincoln Park, and the area around Wrigley Field, called Wrigleyville, are more ethnically diverse and somewhat less expensive. It's also easier to find apartments in these neighborhoods. The northernmost Chicago neighborhood on the lake, called Rogers Park, is even more ethnically diverse and less expensive. It's not as safe as Lincoln Park, but the price and convenience to Evanston make this a popular neighborhood, too. There are lots of great neighborhoods west of the lakefront, but transportation will be more difficult.
Many landlords ask for a one-year lease.
If you rent an apartment on your own, be sure to ask for a transfer clause, which allows you to opt out should you leave the area. Then, should you decide to go to Medill's Washington program or on an internship, you won't be stuck.
