This is a very nice, serviceable apartment close to Gare Du Nord. Note that the proximity to the train means that there will be a lot of activity in front and around the apartment. Train and traffic noise is significant and apt was super hot so w windows open this is something to note. The train station itself is somewhat unsavory, but the immediate neighborhood around la chappelle is more lived in and less sketchy. Also the person in the sofa bed needs an eyemask bc the window shades are transparent and the sun comes in. One key, no keypad so you will need to coordinate. Jackie is amazing - super responsive and available. We had no issues with the check in and they were flexible storing our bags on either side of the trip - city locker is close by too.
