After being stranded in Paris without housing when our earlier host canceled 5 hours after we landed, Jean-Charles really came to the rescue! Communication and was flawless, which was very reassuring after our previous experience. The location in Paris is truly unparalleled as well - a stone throw away from Rue des Rossiers!
A couple things to note about the apartment that didn't bother us, but might bother others, so managing expectations. The apartment is on the top floor and what the french call a "chambre de bonne". There is an elevator (tiny, but score!), but that means on the top floor it's just one room, smaller than a usual western studio. Tall people might be "on top of each other". That means good light though and great views! The murphy bed was very comfortable. We were never there so it didn't bother us, but for some travelers who might not be as easy going or require more space, this might not be the best fit.
All in all, we really enjoyed the apartment and would stay there again! Merci encore Jean-Charles!!!
