The location is perfect, whether you're in Paris because of the museums, because you want to eat well, or you just plan to walk around and enjoy the city.
It's on the fourth floor, which means that it's quiet and full of natural light -- if you want to spend a day in bed just reading and recovering from a tough year, it's perfect. (If you're worried about the "fourth floor without a lift": just carry one bag at a time for each floor, and it's not too hard. A backpack is probably even easier.)
The kitchen works well -- no microwave, but there's an oven and a few pots and pans, so you can reheat almost anything. There's a kettle, and down Rue Vieille du Temple there's a wonderful tea shop too. ;-)
Arlette is a lovely host. It was my first time in an AirBnB, and she took care that I knew everything I had to do. She kept on worrying that the place was smaller than I expected -- but there was room enough to rest, to eat, and even to work a bit.
