Of course, you could take the Metro and a "pesero" (little vans that run bus-like service) down Avenida Insurgentes. Metro stops are ideographs (-gram?) and differing lines are easy to follow. Pesero is very cheap cost in few $ (Mexican ones). Drop off right in front of Ibero. Nice.
Neighborhood NOT nice. My nephew was robbed only four times (knifepoint). Campus is lovely and most people friendly. Bring your Spanish with you and enjoy!
I do not intend to offend you, but I was strongly recommended not to use the metro or public transportation in Mexico City; especially not with my baggage, notebook case etc. looking like a tourist.
