Christian's apt is an authentic old Parisian apartment that he has made as comfortable as possible for travelers. He has left very clear explanations of everything which we did not see at first. He was out of town but was very quick to respond. The metro closest to him was closed but the next ones are not too far. The neighborhood is very touristy which grew on us after a few late nights at jazz clubs and "fast food". There is so much to do in a few short blocks!
