It was a pleasant stay, after we cleared the cluttered kitchen desk - all the amenities such as microwave oven, coffee machine, electric kettle and the like found their new place in the locker below the window (behind the table) and the kitchen became fully operational. The room, about 8 m x 2.5 m, is a mansarde one with low ceiling in the west and in the east, which actually did not matter much. The bed was OK, we had it stretched out at all times.
The only really dangerous obstacle, if you like to cook, is the corner of the hanging shelf above the two electric hobs of the kitchen stove. It is exactly in the place where the cook's head would be while cooking. If you put something in the pot and lift your head you will get a sharp and very painful kick in your head, unless you take great care to avoid it. My better half was constantly reminding me of it and it paid off while she got a good punch twice.
Otherwise the stay was a very peasant one, the location is superb, the Carrefour City supermarket is 5 minute walk away, Louvre, Musee d'Orsay, Les Halles shopping area and Ile de France are all well within walking distance. Would come again, recommended.
