Beware that there's an elevator in the building, but to get to the room you need to go upstairs one additional narrow stairwell, so carrying a heavy bag is not convenient.
The place is really tiny, I don't think there's a room for 2 persons.
The room is clean and cozy. Frederic is a great host going an extra mile all the time. There's a restroom, shower, fridge, microwave oven in the room. Neighbourhood is perfect. Overall experience is very good, I had an excellent holidays in Paris.
