Christians Airbnb is really nice. The Eiffeltower was very close to the apartment (5 Min Walk) bus station is also very near and other attractions too. All in all a very nice stay and I would recommend it, if you want to travel with your family.
Only thing that wasn't good was the one small bed underneath the stairs. It was very hard and the spring was hitting my back. Also when someone in the first floor used the toilet you could here the water in the tube flashing down.
The living room was very nice and big so you could actually sleep all upstairs if you put the cushion upstairs.
The kitchen had everything we needed. For other who love coffee they have a Nespresso machine so don't forget your caps! (We forgot because we didn't know he has it)
Only thing that I personally didn't like was that he provided only one key to the house. so if you split you always have to wait for the other if you don't have the keys.
