If you are near Gare du Norde (or Est) and need to get some laundry done, this is a great…read morelaundromat to do it in. It's not exactly the cheapest place to do laundry on the planet, but the machines function well and are clean, the inside is comfortable enough to wait for your clothes to be done, and the hours are good. For the average traveler, the "7kg" machine for 4 euros (around $4.50) is probably more than enough space for a suitcase full of clothing. Depending on whether you have the ability to hang up clothing in your hostel/hotel, your drying needs might vary, but I was able to get my clothes mostly dry for another 3 euros. Along with soap, that's about $10 for a full load. I would recommend bringing your own soap, especially if you prefer a more natural detergent: the stuff they sell here is sort of weird and has a strong fragrance. While this place might be an expensive choice as a long-term laundromat, it was a completely acceptable place to do one load of laundry mid-trip.
