I transferred to CU Denver from the University of Denver (DU) and am currently in my sophomore year.
The campus is pretty conveniently located in terms of public transport, which is good because the cost of living in Denver is extremely expensive. However, the traffic on campus for drivers can be pretty bad, so you have to make sure to leave extra time in your commute schedule. The dorms are decent, but expensive, and could be more ideally located. While the nearby train stations are convenient, the constant noise from the trains and the somewhat shady area the dorms are located in (under the highway and near a bunch of parking lots and warehouses) make them almost not worth the fifteen minute walk to campus. Almost.
Overall CU Denver is a pretty good school, especially for the price, with diverse students, faculty and classes. I've loved all my professors so far, and loved most of my classes (except for math) and would recommend the school for anyone who can afford it.
