looking for a host family in Petersbourg

Hi every body!

Next year    (from september 2008 to January 2009) I'll have to do a stage in Russia in an university. My university in Brussels have some places for students in 2 universities in  St Petersburg and have place in a student's residence. But I would rather live in a family to have more chance to speak russian than in the residence where all the stranger are put together and so speak english all the time... Could somebody help me? Thank you very much!

Hope to hear from you soon!
