Travel / In Poznan 8-11 August looking for things to do and a cheap place to stay... [3]

Hi

I'm finally coming back to Poland as I havent been back since New Years Eve which I spent in Lodz. This time I'm going to Poznan, could anyone recommend places to go? special events? clubs and bars?? cheap apartments for my short stay?? I've been to Poland many times and love the place. I've read on here that some people can be unfriendly in Poznan? is this true? I've never experience any problems in Krakow or Lodz before but suppose you get odd few idiots everywhere. Really looking forward to finally seeing Poland in summer as its always freezing when am there ha ha

Thanks
