Visiting Belgium & this place was perfect - You can purchase the washer and dryers with your card…read moreor euros. The only downside is you need coins to purchase detergent & and fabric softener (not a big deal but would be perfect if the vending machine for soaps was card too.
4€ for a small load (7kg) & 8€ for large wash (14kg)
The dryers are €1 per 8 minutes.
Instructions are in multiple languages & the machine accepts large bills (but you have to purchase something for it to break your bills).
Very worth it, I'd plan on spending 1-1.5 hours here (we also felt fine to leave while washing). This is right next to the shopping hall too.
