Paris was a very, very close second to Amsterdam for me. I just loved the place. The people were friendly, the food divine and the sights were amazing.
Next time I went back, the husband was with me and he loves it now too. We've been back once again since then and I probably could convince him to visit it again.
I made sure my girls got one trip abroad before they went out on their own and we went to France - mostly to Paris. They all loved it too, especially my eldest.
