We really enjoyed our stay at Cat's apartment. The apartment is very artsy and nicely decorated. It is also very clean and organized. I like it that even though it is in the very dynamic and diverse neighborhood, you can always find peace and comfort in her place. The location can be a challenge, but was not a problem for us. Each day we planned ahead where to go and try to come back before it is too dark and crowded with people and their "business". The perk about the location is that it is close to the train station (making access to and from CDG easy), supermarket and most importantly, metro (La Chapelle and Barbes). I would recommend Cat's place. It suits those planning to staying out for the day and come back not too late.
