Hello Ben,
No question - just wanted to say a huge THANK YOU for such a well-laid out, informative website that answers almost anything a traveller to Paris could ask.
I found your website completely by chance as I was trying to find out if I could get to Haussmann-St,Lazare by walking through Gare St Lazare. Your website seemed to be the only one that had this answer. I now know I can enter Gare St Lazare and walk till Haussmann SL.
Thanks again for designing such a user-friendly site that has such good info.
Chris
