Jean-Michel's apartment is one of the nicest we've stayed at in Paris. Fabulous location, right in the centre of the Marais, but very quiet. Most places we visited we were able to walk to. The flat itself is scrupulously clean and tastefully furnished. The kitchen had everything we could want. It was a real pleasure to come "home" every night and have a glass of wine in the surroundings.
Communication was also great throughout - thank you Jean-Michel and Loic!
