I just returned from a week in Paris, travelling by Eurostar from London and staying in a rented apartment in Montmartre. If you're thinking of going to Paris in the near future, I'd be happy to help as much as I can with any questions you might have.
I also have 5 posts about Paris on my blog, with photos, if you'd like a look it's at www.maggiesmagicpantry.blogspot.com
I'm posting today for D-Day, the Paris posts are the next 5. There's also one about Amsterdam, a bit further back.
