laundromats in Thessaloniki, greece?

I know some of the bigger hotels provide a guest laundromat. I don't know of any outside of these hotels. I suppose you could take your clothes to a dry cleaner.....not sure of the cost, though.

There are two in the city center by Rotunda square. One is called Freskada and it is located in 84 Filippou Street. The load costs 7,00EU/load and it is ready within 3-4 hours. The second one is called Oreo mou Plyntirio, at 8 Manolaki Kyriakou Street. The cost is around 7,5EU/load and it is ready within 3-4 hours. Both of them are located around the Rotunda area. and operate on all day on weekdays, half-day on Saturday and closed on Sunday.

There is one in the Aretsou Marina but surely there will be others too closer to center
