We had a very enjoyable stay. It's well situated for restaurants and access to the Metro. Very nice boulangerie next door but note it was closed at the weekend, so we stocked up after they told us that. Access was easy, just half way up the first flight of stairs.
We were OK for height of ceilings, but I can see taller people need to take care. Also watch out for the small steps between rooms.
WiFi is a Huawei mifi unit which isn't fast, but a quite acceptable speed.
Good size Monoprix is a short walk away (say 7-8 minutes) and stays open late.
We booked ourselves in for another stay next month.
