We stayed here for 4 days with our three kids ages 8, 10 and 12. The space is tidy but very small. I would recommend it for parties of 4 or less and shorter stays (weekend). It was a tight fit for our family of 5. Once the pull out couch is opened there is not much room to move around.
The unit was loud at night because of the bathroom heating and exhaust system. There was also quite a bit of noise and light coming from the neighbors at night. The pull out couch was uncomfortable.
Marie was responsive and very easy to work with. Great hosts.
The location is perfect. It is close to everything you want to see as a tourist in Paris.
The building is beautiful and it felt wonderful to stay in an authentic Parisian apartment.
It was not a perfect fit for our family, but the value was excellent.
