Christian's place is in a great location in Paris. Very central and easy to get to pretty much anywhere you need to go while visiting. Although Christian was away while we visited, he made sure our check in would be easy and made arrangements for a key pick up location. As others have mentioned, if you have problems with stairs this probably isn't the place for you. Also keep in mind that this is a lived in apartment, not a "airbnb hotel" - so be sure to temper your expectations. Overall a good a stay.
