This was a perfect find for us three. The beds are 2 normal European double bedrooms, and there is a sofa couch. Small, cozy and practical - everything expected was there.
location - pretty close to perfect. All the "big" Paris things are easily accessible with a 15-30 min metro/car/scooter ride.
Even better, though, it is close to a small artistic area, with lots of good food places , the little corner bakeries, etc..
Wir definitely do it again.
