I have spend the weekend in Kat and Olivier's apartment and truly loved it. I am a lawyer from London and been to paris many times and their apartment is just perfect location and also very spacious . The photos do not do justice to it. Full of character very arty , very clean and they are so helpful. In the middle of Marais and accessible everywhere and still inside the flat is very quiet. It is a gem . Can not recommend enough. Will go again and again. They should be proud. sadiye
