We stayed at Frédérique's place for a business trip and everyone was very satisfied. It was very close to the Gare du Nord, and as we were all smokers we were excited to be able to smoke at home. But when we arrived the appartment didn't reek of smoke so that was a very good thing too. Also, Frédérique prefers not to wear shoes around the appartment, which was very pleasant for us since we don't like to wear shoes either. Last and most important of all, Frédérique was a fabulous host. She even has a booklet of recommendations of restaurants and seemed always prepared to help us out. I would recommend this appartment to anyone, especially to those who need to stay near the Gare du Nord.
