I've seen

Paris
St.Tropez
Cannes
Venice
Amsterdam
Brussel

and some small cities around.
(and a lot of cities in Turkey)

I can't put İstanbul in anywhere because it's my city. I think all of them are nice, but maybe Paris was the most and Amsterdam was the least I liked among the big ones. I would like to go back to Brussel one day again, because it looked great and I couldn't spend enough time.
And in Turkey, I like Capadoccia (Nevşehir) very much.

Oh and I forgot. Brugge is also a very cute city. You have to see there.

I went to istanbul years ago when i was about 15 and so I don't remeber to much, but i did like it and would love to go back some day.

As for my favourite, it would have to be Paris. Especially if you can share it with somone you love.

My favourite city in the world is Barcelona – I love that city!!! And I could easily see myself living happily ever after there, so that would be my first choice.

And the second choice at this moment would be Istanbul...I am falling in love with her just from her looks and from listening to what people tell me about her... She is really something, huh?

Ofcourse istanbul which is Paradise of the World

Depends if it's for a holiday or to live in.

A holiday? Budapest, Vienna, Istanbul, Paris, London and my favourite Kyoto. All great. Each has it's own charme.

To live in? My hometown Rotterdam (because I know it) but also many other places in my country. No place abroad because I would miss my country too much if it was forever.

I would love to live in either San Luis Obispo, California or Buenos Aires, Argentina. One is small but gorgeous the other is enormous but just as beautiful.

1) Cambridge UK, a very cosmopolitan city with beautiful achitecture, historic universities, lovely river with punts to hire, great restaurants and bars.

2) Istanbul - city of intrigue and fascination, historic and awe inspiring architecture.

3) Hong Kong - mystical, with a great mix of oriental and modern, a 24 hour night city that never sleeps!!

If we're solely talking about big cities, I'd have to go with Istanbul. It's a fantastic city to me, but maybe that's just because it's the city where I fell in love Also I find London quite great, probably because people never take me for a tourist there I hate being called a tourist.

Cities that have disappointed includes Paris and Miami. Paris - well just not my cup of tea. And Miami - it's just impossible to get anywhere on foot, you need to have a car at all times. That's one thing that's great about Istanbul, even if you've walked a couple of kilometres you feel it's much less because there's something to look at all the time.

There are nice things to see in most cities, but I have mostly been disappointed by most big cities. This includes Paris, Istanbul, New York. I've been very disappointed by their dirtiness and chaos and by the things that are admired by other people. While the architecture of Istanbul is great to see for Europeans, it didn't leave a lasting impression on me. The same happened when I went to Paris, not to even mention New York which was such a disappointment to me. I don't like old, crowded cities.

The ones I liked most were Krakow, DC, and some German cities. Krakow is beautiful and has so much history, coziness and German cities are clean and cute. DC was the most cultured city I've ever seen. It's very classy there.
