The drop-off laundry is situated in a courtyard behind the supermarket. You may have to ask directions, as it is not well marked. It might be Valalta's best kept secret.
I handed in a large sail bag of laundry(10 or 15Kg)and it only cost me 36Kn (€5). It was ready the next day and nicely folded.
Best deal anywhere in the Med.Howard [ Just Imagine ] 18-Oct-2007
