We spent a wonderful weekend at Elie's place. He had sent us all the relevant information a couple of days, including alternative contact numbers in case he was unavailable. He was fine with letting us check in early, and his brother Adam was available to check us in, as well as give us a tour of the neighbourhood.
The location is excellent - a few minutes walk from the Eiffel Tower, a little more to the Louvre, etc. Rue Cler has a variety of good dining options with nice cafes, produce stalls and grocery stores.
Overall, I would recommended without hesitation.
