Well...
Warsaw is a very nice city, on the other hand the mainbase of wizz is Kattowice, so if you would like to fly many routes, Kattowice is the first choice.
Poland has recently joined the EU.It`s eastern Europe ,normally it`s quite cheap there.The average salary in 2006 was 200 euro/month.(but you need much more than 200 euros!)
Because of the EU the prices are raising now.Especially in bigger cities (worst situation: Warsaw).But if you compare the prices with middle Europe ,(Germany, Austria etc..) it`s quite cheap.
If you would like to move to Poland,the salary being paid is quite ok, so you won`t have any problems.
Wizz air do also have a base in Budapest,but newcomers have to go to Poland as they don`t need pilots there.
