Marie is a very nice and friendly host. The house location is very near to Eiffel Tower, about 5~10minutes walk. When we arrived in Paris Nord TrainStation, Marie suggested us to use bus no.42, which will stop nearby her place (on the bus route). I recommend to use this bus for sightseeing as the bus route covered most of the famous spots in Paris. However, please note that the bus schedule is unreliable. We ended waiting for more than half an hour. There is a train station nearby as an alternative.
Marie offered her daugther's room which is quite spacious for two of us. The two single beds are comfortable. The blanket and pillow are good too. You can ask her for more if you need more. Toilet and shower are separated. Two thumbs up for the cleaniness.
If I have to comment the negative side, i have to say that wooden floor made quakey noise when we walk. It could disturb Marie or the neighbour when we walk to the toilet or kitchen during the night.
I will definitely go back to Marie's place if i have chance to visit Paris again. Miss the crossaints and patries. Ask Marie about the bakery shop. Nice! Thanks Marie!
