Catherine’s apartment was absolutely fantastic for my family of 6! We had plenty of space to sleep and eat together and the location is far enough away from the tourist-y spots that you feel like a real Parisian. It’s close enough, however, that we walked to Notre Dame and St.-Chappelle in around 20 mins which was a great way to see the streets of Paris. The transportation strike was continuing, so I can’t talk about mass transit, but we were still able to walk to the 1 line (which is operational) and get to the louvre and champs-elysees without any difficulty. Would stay again for sure!
