Be prepared to never get your money back with these thieves! I lost coins in the dryer and left a note and e-mail, but not even a call or reply. Go elsewhere please. Useless business.
Spin King is a good laundry, as laundries go. It is unstaffed, but is kept very clean and is open 24/7, which is super handy. Prices are reasonable, with a load and tumble dry costing around $6 generally. The one big drawback is that there is no change machine, so a trip to the pokies over the road is necessary if you don't have the coins on hand!
Approximate cost: $6
