The location is excellent, near the metro and many cafes/restaurants. Unlike some Paris Airbnbs, they provide towels, shampoo, and soap. There's only one toilet, which was somewhat inconvenient. But excellent showers and hot water. Other than the toilet situation, it would be great for two couples max. The apartment is on a quiet street facing the courtyard so there's little noise. And the bed was surprisingly comfortable!
It was quite really quite suitable for our purposes as we spent most of our time wandering the city.
