Nicolas was a very nice host and has a lovely family.
He wasn't able to receive me but his lovely wife does. Unfortunately she doesn't speak English but the communication went very well.
The room and private bathroom with toilet is very clean and comfortable. You can share the kitchen with them, but I haven't used this because I had breakfast, lunch and dinner outside.
The location of the house is very central. You can take any public transportation to go anywhere in Paris.
I heard his kids in the morning preparing to go to school, but I didn't mind because I'm a good sleeper.
I enjoyed my stay and would recommend this place.
