I was there in December and January of 2008. That university is very good, also many Korean students there. The temperature is around -20-35 degree. But if you well enough clothes, glove, mask, scarf, everything is ok. Snowy+ icy. You could also find many Russians on the main streets, they have Russian style churches, shops, buildings. The food is not expensive and of great amount. Don't worry, I bet it will be a nice experience for you.
