This apartment is highly convenient to Gare du Nord train station. Charming building and stylish apartment. Lots of street noise from taxi queue, but it is central Paris, after all. Check-in was very streamlined. Great recommenations for local restaurants.
Only concern was that the second toilet didn't work. The hostess didn't avise about this until after check-in. I requested a modest credit through the Airbnb app for the inconvenience, since we paid more for a large apartment with multiple toilets for my entire family. Unfortunately, the hostess didn't accept the request for the credit.
