I currently live in Louisville--in Old Louisville, to be exact, which is the neighborhood directly north of campus, easily within walking or biking distance if you want to go that route. I've never attended U of L, but my husband and I live in Old Louisville because I'm serving with AmeriCorps, and you can find very affordable housing near the university. I have never had any safety issues in Old Louisville, and I appreciate its economic diversity, which is hard to come by these days. Because it is a historic district, there are many wealthy residents who maintain massive Victorian homes, as well as many low and middle income renters scattered throughout the neighborhood. I take the bus every day to and from work, and have never had any issues. If you want to live near campus, I would suggest living in Old Louisville, and if you want to take the bus to campus, I would suggest living on 4th street, which is one of the only two-way streets in the neighborhood, with buses heading to and from campus pretty regularly. Additionally, Central Park is in Old Louisville, which has a full playground, an open air-stage (for Shakespeare in the Park during the summer) and lots of space for walking dogs.
