Pittsburgh is an awesome city, I stayed there in 2011. It's sort of depressing though, almost everyone you meet is an alcoholic or a heavy smoker and the vibe in Pittsburgh isn't a great one. I still love it as a city. I think the downtown is pretty too and very well kept. Don't forget this too, Pittsburgh used to be the top city in the country where steel was produced. Buffalo, NY is the same, and it's even more depressing than Pittsburgh.
