Hello Aysun. Good notebook entry. There are minor grammatical and spelling errors. Moreover what I don't understand from the write-up is that 'whether you live in Istanbul or you visited Istanbul after a long time'. I used my own judgement to correct the entry. Please feel free to contact me and send me a message. Consider the following:

"I have not travelled  to Istanbul in a long time. Sometime back I visited the city again with my daughter. Everything seem to be the same as I have left. It is a wonderful city."

or

"I have been living in Istanbul for a long time. I visited the city recently with my daughter. Everything was same as I have left. What a wonderful city it is."
