Study / STUDY ABROAD in Krakow. What's the area like (and a few more questions). [6]

I attend Western Illinois University in Macolm Illinois and I am looking to study abroad in Krakov Poland. I have a few questions: One what is the area like? How much will it cost me to stay? and will it hurt me that I do not speak fluent Polish? Any advice you can give will be helpful.
