漢語, correct it please.

我是/叫Balazs，我二十八歲, 我會說一些/點點/漢語句中文。我[Here you can have it because many phrases had gone before and doesn't sound so repetitiously]住在匈牙利的首都，布達佩斯。[我]喜歡聽音樂和看電影。

In Chinese, you don't need to use pronouns so often when the context is clearly understood.  I'm sure it must be in Hungarian too.  Makes your writing very child-like.

我是Balazs，我二十八歲。（√ another expression:我叫balazs,我今年二十八岁了。）我會說一些漢語句。（the more suitable expression is:我会说一点点中文。1.Chinese native-Speaker usually use the word“中文”instead of“汉语”;2.you should remove the character"句“，because it‘s duplicate.） 我住在匈牙利的首都，布達佩斯。我喜歡聽音樂和看電影。(√in these two sentences,"我”as a subject in each sentence,your useage is correct. Jeff says right too,but it's not a big deal then)
