I agree with others leaving reviews before me: Ben's apartment is as lovely as you can expect from the photos and the location is perfect for Paris sightseeing.

Ben responded me always promptly in English.
He greeted us at the apartment and even was flexible to change our agreed meeting time on a fly. We also appreciated the possiblity to check-in earlier, so that we were able to leave our luggage to the apartment before the official check-in time while the cleaner was still tiding up the apartment.

I'll highly recommend this apartment and I would be happy to stay there again.
