It depends on the University. They are all different. Usually the people are nice, especially to the foreigners. But I can speak only for St. Petersburg where I live. But the real problem is - the LANGUAGE. I'm not sure that there is going to be a special English-speaking teacher for you, it's good if it will be like this. But if the education will be in Russian - you have problems, the language is very complex and it's especially complex when it comes to science and education. If you are interested how the life in Russia is - it's absolutely normal, especially in Moscow, no different than London or Paris. The city is very big and developed.
