We did the Louvre in an hour with Antione with my brother and sister-in-law. It was PERFECT - Antoine was knowledgeable and we spent a great hour seeing the highlights of the Louvre. Antoine had stories about the art which deeply enhanced the experience. The Louvre can be so overwhelming because of its size and the amount of art - with Antoine it was an amazing experience. Antoine made the whole thing easy - he already had the tickets and English brochures and maps, and then we had time afterwards to keep exploring on our own. Highly recommended!
