Have a wonderful trip !!

Lucky you !    :-)

Try www.couchsurfing.com which I think is better geared up for what you're proposing in the timeframe you've got. There is a section for meeting people. Also try www.meetup.com and see if there are any English/Italian language exchanges.

Hopefully you'll get a response here.

Enjoy Milan!

Please dont be shy! 25 'reads' but no replies! Does anyone live in Milan looking to language exchange English?
