I stayed at the Concorde Lafayette with my oldest daughter during Spring Break. They gave me a rate of 75 euros per day including the free breakfast for both of us. We stayed two nights and the total bill at checkout was 150 euros with no additional fees or taxes. I was expecting to get hammered on taxes but the rate quoted to me was the total inclusive price. Now I'm not saying this is the best hotel in Paris but it is conveniently located, one of our layover hotels and the price was definitely right. I did the entire transaction via email correspondence with the hotel about 45 days in advance.
