I highly recommend booking a stay at Francois Xavier's apartment. It's spacious, updated, comfortable, and modern with a terrific view of the Eiffel Tower. Exploring Paris beyond his apartment is so easy with two metro lines a block away from the front door.
He's friendly, super responsive, and helpful. Despite his excellent directions from CDG, I managed to get off at the wrong metro stop and he came to find me and walk me to his apartment.
His apartment is awesome and he is awesome, two thumbs up!
