We did not meet Francois, but his friend Samir was great. He was very accommodating of our schedule, despite a slight miscommunication on our part.
The location was in the garment district and very close to a metro - lines 3 & 8. If you don't mind a little distance, you can also walk to the Seine. The address is D'Aboukir not Aboukir i believe.
There is 1 bedroom off to one side of the apartment which you enter through a library where there are bunk beds. It was perfect for our family of 4.
Also there is a washer/dryer, but you should ask for instructions if you don't speak French or your clothes will never dry!
All in all a great place to stay, but hope you have better weather than us!
