I'm in Moscow for only 2/3 weeks now, and I'd really like to improve my russian by doing a little course, or some individual classes with a russian native teacher.

I've searched about some schools, but all I've found so far was VEEEERY expensive, and I couldn't afford it. I'm already on lower intermediate level.

So, do you guys know any russian teacher or school in Moscow with reasonable prices?

Thank you very much!
