Try to use this (unfortunately for you in Polish... events searcher tool) mobiwroclaw.nazwa.pl/kultura/wyszukiwarka_wydarzen.html
maybe this would be more helpful for english speaker: radiowroclove.com
anyway, May is Juwenalia month = student parties and festivals, I suppose as usual a lot of concerts is taking place right now (I'm off the town for some time so don't know what is on the posters...)
I have been in Wroclaw couple of times before and I do know some places. But what I tried to ask in my first message was some direct hits to my mail box.
I am not seeking for cultural events nor weekend happenings cause I will be there from monday to friday. Reason why I ask, is that I don't want to spend my week for looking.
I noticed last May that there were lots of students around... Party and beautiful Polish ladies sounds good always!
How is the evening/night life in the summer, is it mainly oriented to early-20's or will an ordinary guy like me who's already in his late 30's mix in without standing out desperately outdated?
Is Wrocław a good destination around this time of the year, or have most of the students and other fun-liking people travelled away for their holiday/summer job, leaving just German tourists in the downtown?
