Absolutely the best place we've stayed in Paris and would return to the Blue House without hesitation. The location is ideal, and the street is one of the quietest of Ile Saint-Louis. Our family of four had everything we needed in a cleverly-designed kitchen. The bathroom has modern updates, with a fabulous shower. We appreciated the Nespresso machine and coffees provided. We were in Paris during a warm spell, and I was concerned about lack of air conditioning, but the apartment stayed cool (ground level), and the owners were kind enough to provide a powerful fan for us just in case! I'm feeling nostalgic for Paris as I write this even though it's only been two days, but we will hopefully return in the future.
