But thank you you told me about negative things and now the positive ?

Really ^^ But I don't care I don t love football so I have no problem with stone age people, I'm here to see the culture of my ancestors and they are not tramps and dilapidated buildings that will scare me ahah 
 

I would recommend Krakow you can always get some fresh air here, bring home a piece of plaster from the crumbling building as an exhibit, meet interesting people sleeping on the benches sometimes you can get something from them as a gift, quite often you can see here free presentation Stone Age people running around with machetes, hunting for game :)

Yours resident of Krakow

ok thanks
Kielce because I have got family in kielce :) 

Kielce??? Every city you have mentioned is awesome (especially Krakow and Wrocław are unique and magic) but Kielce... well, I don't recommend you this town.
