Nov 11 is a National Holiday in France: Armistice 1918
The Airbnb Open will start on November 12, 2015, but a number of hosts already arrives earlier in Paris; there is even a pre-check in on November 11, 2015. Please don't forget, that Nov 11 is a National Holiday in France (Armistice 1918). It marks the end of World War I and commemorates those who were killed during the war.
Opening hours of shops, schedules of trains, and other facilities' availabilities may change.
There are also "private" ATM's in shops; usefull if you find no "official" one. But they charge an extra commission.
BTW: Never accept that the ATM's local provider "guarantees" the exchange rate. Often you have the choice between the withdrawal act performed in EUR or in your original curreny. Take the EUR rate, and let YOUR bank do the converting calculation. It's more reliable, and cheaper.
