We had a great stay! Pierre couldn't be there personally but he explained everything perfectly by message, we had no problem finding the place.
The apartment is exactly as described, it's small but very cleverly decorated. We stayed there with 4 persons and we had enough space for all of us.
Pierre is a great host, really friendly and helpful! Even when we had small problems with the keys, we could reach him immediately and he made sure everything was fixed in less than half an hour.
I would definitely recommend this place when visiting Paris!
