Those of you staying in a Paris for a few days would be wise to learn to use the Metro... It's fast, convenient and inexpensive... Paris is a large city... Even the areas you want to see within the historic center can be a lengthy walk...
Lots of folks complaining lately about the cost of cabs & Ubers in Paris... It's just like NYC... Big city, and lots of tourists... If you're gonna take a cab, ask the cost before you get in the cab... "how much to take us to..." Make sure to use "real taxis" not hackers, they'll rip you off... And if they tell you it's metered (have your GPS out and watch where they're taking you... or one of my favorite things to do when you get into a cab is to show them on your city map where you want to go, so that he knows you have a map! (they'll give you a really nice city map if you're staying at Hotel Londres de Eiffel) Also good to let taxi driver subtly notice you have your maps program open on your smart phone... But if you want to save $$$, learn to use the Metro!
By the way, and this is important; keep your ticket even after you exit the Metro! they've got Metro Police that do lots of random checks to make sure people are paying and not just jumping the turnstiles... If you don't have your ticket or your Navigo card, they will fine you on the spot 35 Euro and they catch a lot of innocent people who didn't know to keep their tix!
