Sebastien's space was exactly as advertised: spacious, charming, stocked with everything you need, and one of the best locations to stay in the Marais. But more importantly, Sebastien was the ultimate host, maybe the best we've had so far - extremely proactive and communicative, answered any questions we had almost instantly, and warning us ahead of time for anything that was happening in Paris that could hinder our movement. We extremely appreciative of his support and his wonderful space, would definitely recommend to anyone!!
