First, Christophe is a very nice person who is always caring about you and attentive. Once you come back to his place he would make sure that you are feeling good.
Second, his place is convenient especially thanks to some metro stations nearby. In addition to it, you can find some bakeries with tasty bread and pastries.
I would highly recommend you to stay at his place if you want to make your trip to Paris more unforgettable one :)
