This is a great little place. It's very tiny, but has everything. You can wash your clothes and dry them either on the warming towel rack or by air. You can cook, with pots and pans, and plenty of utensils to use.
It's six flights of stairs up on a narrow circular wood stepped staircase which I found fine, even good as it's good exercise. The 95 bus is half a block away which takes you right through the main parts of Paris. I was on it often. There are also three or four metro lines you can get to within not too much walking distance which means you can get to many different places around Paris. I was there for almost four weeks and loved it and would definitely stay there again.
Shower is really nice, new tile, clean, and just great, also. Just a great place.
