"Polish Language for foreigner" classes?
Yes it does. I learned basic conversational Polish at one such place. It was a three week intensive course, five mornings per week. It was a very small class, only five of us, all different nationalities, French, Irish, American and Thai. At the end of the three weeks we had all reached a point of being able to communicate in Polish for everyday purposes. It was really good. The place I studied at was called IKO, The Institute of Polish for Foreigners in central Warsaw. All the teachers spoke very fluent English so they were able to explain grammar etc to us but mostly we did a lot of talking in Polish so I would highly reccommend it. I see that they are also offering one-to-one Skype lessons now.
