What a FANTASTIC space! (Okay, the 4 flights of stairs were harrowing at first, but I got used to them.)
The bed is firm, but comfy. My son slept on the couch in sitting room, and he was comfy. The tv stations were all in French (duh, Paris!), and I meant to ask if there was an English station, but I really had no time to watch tv anyway. (duh, Paris!)
Kitchen was great, though we didn't cook much. We ate breakfast in, then most other meals out. Fridge was a perfect size; Freezer was very big for an apartment that size.
There was an excellent washing machine. I was concerned that there wasn't an electric dryer, but the washing machine spun the cloths out so well that they dried fairly quickly when we hung them out.
The apartment felt like a home. There is a wall of books, a couple of plants, interesting knick-knacks, and intriguing framed art.
The apartment is very close to a metro station, which was a life saver. There is a largish grocery store down the street (Monoprix) and a much smaller one across the street (Carrefore?). There is a super patisserie that was unfortunately closed on Saturday and Sunday.
TLDR: Super place, super experience. Thanks for all!!
