Is racism towards blacks a problem in Poland?

I'm of German and American decent, but my cousin and I are going to Poland in about a month. To do some sight seeing and hopefully some skiing. But he is Black. Now my umption is not coming from Poland, but from Eastern Europe in General. Which it does have major racism problems all through out Europe, but the worst I've seen have all been in the Areas such as Russia, some time spent in Sarajevo, and Albania. Now where going to be splitting the price for some apartment out in Warsaw I think, but I'm curious if we are going to have any problems with his skin tone?
