Oliver and Florence are great host's in that they have great recommendations, and will do what they can to accommodate you. What I will say is their place and neighborhood is more family oriented, with a few great cafes nearby as well as the metro. Additionally while they were accommodating in the times I would leave and arrive I always felt bad as I'm a night owl and like to be up late and I tried to be quite when arriving at 12 or so. All in all if you need a great value near the Eiffel this is a good place to start.
