Laundry City at 632 Grand Avenue, Brooklyn, New York.

The employees are awesome. It's clean, not too pricey, huge.

Wifi and restroom, this laundry mart is the cheapest in the neighborhood, even with the $3 refundable card their machines use. A $20 bill onto the card will get you $2 extra free! Just don't go on Sunday afternoon when it's crazy busy. Any other time there are plenty of open machines. When you go to dry, pull the lint drawer out and empty it before starting the machine, your clothes will dry in about 30 minutes.
