I can only say, that the trip was wonderful!
The guest room ist very beautiful, tidy and clean.
The backyard where you enter the room ist absolutely beautiful too and you feel very comfortable.
The hosts were so nice and friendly!
They let us feel welcome and we could set aside our luggage before and after we got into the room.
The situation of the house is very good.
Right next to the guest-room are two métro stations.
The environment is extremely beautiful and less crowded than the center of Paris.
I can only recommend this place and have nothing negative to add.
