Paris Pratique - Le Metro
Just about every tourist I know loves the Metro. It's practical and quick. But, how quick? I never knew how much time I would need to get from point A to point B. One day, a Parisian friend gave me this helpful hint...
"Allow yourself 2 minute for each station and 5 minutes for each transfer."
I tested her method for nearly a year and found it to be tremendously accurate.
