If you are renting your property it's best to get an agency to look after it and they will handle the laundry.
There is a laundry in Calis, we have used this laundry for sheets and pillow cases, when we first bought our place and made the mistake of buying the local white cotton sheets etc., which are a nightmare to iron.
Walking up the Main Street from the prom keep on the right and you come to the road on the right. Scarletts is at the bottom of this road and Pastries and Pies is on the left. The laundry is on the right hand side. They are good, but I don't think they will pick up and deliver, but you could ask.
