Very good service, perfectly working machines and easy to use. Most importantly, always open! I could laundry my clothes after a wet hike on January the 1st :)

This place is quite literally the only place in town for 24/7 do-it-yourself laundry. Bus stops right outside. Coffee bar two doors down. Cold wash in a large (read standard American size) washer is 5€. Price depends on size of washer and temp of water. The dryer is another couple € depending on time. The system is interesting. Windows touch screen, Greek, English, Italian, German and some others. Laundry detergent available for purchase. The machines are new and my wife says "it feels safe". The owner was extremely helpful, friendly atmosphere. If you're a smart traveler, packing light and planning for a couple hours to wash, make sure you have this place on your list for Herakleion.
