My BF and I stayed at Christine's flat for 5 days. Our experience in the flat was so comfortable and perfect situation for as if we are living in Paris. The building has easy access(secure) to the room and nice neighborhood with two close metro station, grocery store, and cafes. We loved the large fluffy couch in the flat after coming back from the center of the paris to relax. Christine prepares good kitchen utilities, washing machine to use, clean towel and so on. we loved how she decorate her room, very sophisticated. I recommend the flat for one or two(BF or couple) as for the bed size.
Christine takes care of us good, even though we didn't get to meet her. She communicates us via email with detail instruction and must know about her place.
Overall, we had the best experience in Paris by staying at her flat. I would choose her place if I come back to Paris again.
