I did not meet Jacques in person but his girlfriend Sabine, was waiting for me at the apartment to give me the keys.
The apartment is small and clean. It fits a couple.
It has all the basic comforts to spend a weekend in Paris.
It's well located: 200m from the metro Pasteur and 40 min walking from the Tour Eiffel.
The only bug was Internet, that was not working due to an Orange problem.
