My husband and I spend a weekend in Paris in this lovely flat at the Marais. Marie was super helpful and thoughtful, responded very quickly to all our requests, and was flexible on the check in/out times which was very helpful and contributed greatly to our stay.
The flat is lovely and exactly as seen in the picture, and the location could not be better. The bed was super comfortable and the area was very quite during the night, allowing a quality sleep. The only thing to take into account is that there is a cat that probably living some of its time there. He wasn't around during the stay (although we would love its presence around as we love cats), but in case you are allergic or sensitive to presence of animals take it into account.
