We had a wonderful stay at Jean-Claude's apartment. The views are absolutely breathtaking, especially at sunset and with the light show on the Eiffel-Tower following - you have to experience it yourself!
Jean-Claude organized everything perfectly and was very responsive to all our inquiries. The apartment itself is clean and perfectly suited for travellers, providing everything you could ask for from washing machine to full kitchen equipment etc.
The location is nice, being two minutes away from the Coulée verte René-Dumont, a green parkway planted on an abandoned elevated railway (similar to the Highline in Manhattan) which leads you from another angle through typically Parisian architecture directly to the Bastille.
