Vanderbilt, Tulane and Emory are great suggestions.(Vanderbilt - heart of Nashville; Tulane - in Garden District/ Uptown, on streetcar line; Emory - Clifton Rd. [CDC, Emory Point] / N. Decatur Rd [Emory Village] are urban; Atlanta Virginia Highlands and Little Five Points neighborhoods are 5 minutes away.)
Also: University of Chicago
Northwestern (Evanston is just over the Chicago city line and parts blend into Chicago, also with El stop.)
The Ohio State University (Columbus - High Street)
College of Charleston (King Street!)
University of Miami (Gated campus - right outside urban Miami, Coral Gables)
SMU (Dallas)
Trinity University (San Antonio)
