We stayed there for a few days in October. The apartment was perfect, very cosy, comfortable and clean! Maxim was very welcoming and hospitable, and gave us great recommendations to explore the neighborhood. The location was perfect as well, the Ile Saint Louis is charming with its small, old streets and buildings and gorgeous views. From there it's an easy walk to other great neighborhoods in Paris, such as the Marais on the right bank, or Saint Michel/Saint Germain on the left bank. Great experience all around!
