Despite it's small size, Jeremie's place has everything you need for your stay in Paris, whether it's just a few days or a longer trip! Everything was very clean and it was easy to find thanks to the detailed directions Jeremie messaged me beforehand. The water pressure was great, the bed was comfortable, and lots of thoughtful little extras were included, such as coffee, hand sanitizer, etc.
The apartment is a 30 minute walk from Gare Du Nord in one direction and 30 minute walk to Le Marais in another (which was one of the areas I was most excited to explore).
Be aware that just one block down near the metro station there is an area where several homeless people set up their tents and mattresses, but I was never bothered or even approached by anyone. I actually felt very safe as a solo female traveller even walking home from a bar after midnight. Just stay alert and trust your gut.
