For me the key thing about Sebastien's apartment is that it is incredibly comfortable. I was in it for a month and after a few days it truly felt like home. Well not quite because this is a super location in Paris.
And Sebastien is the super host of super hosts. This is the second time I've rented from him and again he really earned his wings. I arrived brain dead from lack of sleep and had some trouble getting into the building. So I called him and left a message and within 30 seconds he got back to me. Terrific!
