Great location and Catherine was a great host. We left after two days (half of our stay) for the hotel next door because the dark bohemian style did not suit us. There are 7 lamps in the living space and 5 lamps in the bedroom so turning every one on and off if you require light could be a chore. Apartment has a few details one would expect in an older building: small kitchen and fridge (microwave is on a shelf held up by wine bottles), erratic water temperature and pressure (hand held shower in small tub), 4 flights of stairs to the top, old furniture and low ceilings. This could be your dream stay in Paris because of the fantastic location and host, just be aware of the bohemian style.
