Mention what you know about it, what attracts you, and what you would do there.
You can record an answer, review the transcript, compare it with a stronger sample answer, and retry the same prompt without losing the main idea.
A city I would really like to visit is Tokyo. I have never been there, but I have seen many videos and read a little about it online. What interests me most is the mix of modern life and traditional culture. It seems like a place where you can see tall buildings, advanced technology, and also quiet temples in the same city. If I had the chance to go there, I would like to try local food, visit famous streets, and experience daily life there. I think this city attracts me because it looks very different from where I live now.
This answer is around Band 6 because it stays focused and easy to follow, but the vocabulary range and examples could be more precise.
