I don't have much to give in terms of the faculty. I've only recently begun to study the region (in fact, just started in my senior year). Most of my interactions have been within the literature side of the Slavic department, which is mainly where my interests lie. Like most programs, there is a heavier emphasis on Russian studies, but luckily there are a few professors who specialize elsewhere. My interests are in post-1989 Poland and the effects on literature after the shift (pretty vague at the moment).
One main draw for myself is the ability to take courses at Duke if there isn't something you're looking for in the current semester at Carolina. The two schools do a pretty good job of combining resources where needed.
Chapel Hill is definitely a college town. It's kind of its on bubble between Raleigh and Durham, which is nice. The practically always warm weather is great, too. haha.
