I could never understand why people raved about Paris so much, until I went back more than once and slowly started to appreciate its beauty. Having been there in all the seasons, I can finally say: Paris mon amour.
Is it messy? Yes! Is it chaotic? Yes! But it's also beautiful, charming, romantic, and there's always something going on of course. If you don't like it the first time then don't give up, give it another go.
