    thumb Melanie Pica
  • Unstaffed so you are left to do laundry in peace. Great hours: 5AM - midnight everyday! There is also a few old school centrifuges where you can spin (for 95 cents) your clothes extra fast after wash and save time & money when you transfer them to the dryer. The music is set to easy listening 99.1 FM. Everything about this place is cool. Standard credit/debit card payment for rechargable laundry cards.
