I stayed at Olivier's place for a couple of days. The room is tiny but sufficient for a single traveler. It has a small ensuite bathroom with a shower. The space is very clean and tidy. The flat is located in a residential area, a bit far from the center, but there are shops and restaurants around. It was a hot July in Paris, so the room was somewhat hot. Olivier is nice and welcoming (also he speaks English). It was a pleasure to meet him! Overall, I can recommend this room for a brief stay in Paris for a single person.
