Overall, this place is great for a few days in Paris.
First of all, the location close to the Gare du Nord train station is about a 10-minute walk. You also have a metro station close by (5-minute walk). The neighborhood is great with lots of small restaurants, a grocery store close by and a few cafes.
The apartment itself is quiet and even though is a bit small, it has everything you need for a comfortable stay. It has a small kitchenette with dishes and a few cooking utensils, a small fridge and even a washer/dryer. This place is great for a solo traveler or a couple.
Check-in process, which is self-check-in, is super easy and communication with Remi is great. She’s incredibly helpful and responds right away.
I would definitely stay here again.
