The winter school in UrFU left me an amazing experience.
EKB is an interesting city inside Ural, it's still not so disturbed by the worldwide globalization. So it's certainly a good chance to experience the real Russia in such a special place, especially in the freezing winter))
The Russian language courses they provide were awesome too. They have courses for different levels so everyone from beginner to advanced speakers can improve his language skills.
Also, it's an international school so we had chance to meet friends who are also found of Russian culture from all over the world! I made friends with some local girls and a Brazilian boy, and learned a lot about the outside world.
All the experience the UrFU winter school gave me was so unique. I remember the peaceful beautiful city, the unique Russian food, the passionate friends, the endless snow as well as the wild Siberian forest.
I strongly recommend you to come and experience it by yourself! It's an amazing place worth exploring
