HIGHLY RECOMMENDED! Staying at Marc's apartment gave us a final touch to our trip to Paris. The apartment is very charming, cosy and with very nice details. It seems that they put a lot of care in having it beautiful. It was also very well organized and with space maximization.
The only inconvenience was that it is a bit far from the center however not a reason for not to stay there because the access to the metro or Paris bicycle rental was to close.
