Look for HIDING charges when you exchange money in Paris. Specifically Llword Sarl in Avenue de l'Opera 75001 Paris, France. You could lose huge amount of money for "fixed fees" + "commission fees" + "special exchange rates". And they don't even explain you properly what are they charging you. They just took your money and give you whatever they want for it.

I exchanged 100 sterling pounds and receive just 90 euros. I was expecting at least 115 euros, because that was the money I recieved in another trader.

Be careful. Thanks.
