I love Paris and go there at least twice a year. It will always be my favourite city. It has so much style. I have never had a problem with the Parisians even though my command of French is pretty poor.
I usually stay at the Ritz, Place Vendome when I am feeling flush or at the Westin Hotel which is closeby on the Rue de Castigileone. Both are in the 1st Arrondissement.
There is no point going to Paris if you are penny pinching.
Yes, Paris is very expensive but no more than London, which is a dump. But I don't care, as for me it will always be Heaven!
Sorry to be so contrary. But that's me!
PS: Don't take your car there. It will get wrecked!
