Myself, my son and two grandsons stayed here on our European trip. Louise's place has so much space, everyone got their own bedroom, and the common room was very spacious too. For being above a busy street (during the day) it was surprisingly quiet at night.
The location is great as a base for touring the sights in Paris. We took advantage of the public transportation systems to get us around to all the places on our list. There were stations close by.
I wouldn't hesitate to stay there again.
