Can't comment on your Eurostar question but I saw that you are looking for a studio rental in Paris.

We spent a week in Paris earlier this month and rented an apartment from a company located in Vancouver: France Bound Consulting Ltd. Kerry McKeen, who runs it, is extremely efficient, reliable and knowledgeable. For both you and us France Bound's location here is very convenient. You might want to look at their website which is http://www.francebound.net

We hope you will have a wonderful time in Paris. There is currently a special exhibition in the Picasso Museum. There is also one at the Louvre but you will be competing with hordes of people who would, but for the DaVinci Code, never have gone there. Great revenue booster for the Louvre!

Regards. Howard in Vancouver
