Cracow is surely the most interesting and beautiful place I have ever bee TO.
'What is more' (mozna uzyc 'furthermore'), Cracow is the former capital of the country (ale tutaj ja dodalabym 'of Poland'), which makes it even more interesting due to its history (ale czego? dodac dlaczego?).
What I like about this city is that there are many artists on the street and 'at the market' (nie wiem o ktory chodzi tutaj), so you never get bored there. Walking down the street or being 'at the market' (wytlumacz o co chodzi) you can hear people singing and playing 'some' (zamiast 'some' uzyj 'various') instruments.
