Amazing space and the location is perfect if you’ve been to Paris before. I wouldn’t recommend this place if it’s your first time in Paris just because it’s not too central to things. Everything worked well, do keep in mind about the stairs. We only came for a couple of days so we only brought backpacks, but I would not want to be climbing up with luggage. The neighbors were all very nice and check in went smoothly. My only complain is that it seemed that no one came to clear the fridge from the guests before us and the electric kettle had water left in it with something floating in it. Also there were no extra blankets/pillows, but the heating system worked well enough to balance that out.
Overall I give this space a 9/10.
