Arriving in Chester with a lot of dirty clothes, I found the Garden Lane Laundrette, 56 Garden Lane. It's convenient to the central tourist area (a brisk 10 minute walk from the clock), opens at 8:00 am, and, best of all, they offer service washes: GBP 8 for a small load, GBP 9 for a large load. Drop the wash at 8:00 and pick it up later, washed and neatly folded. If you prefer to do it yourself, they have coin machines and internet. But I like the service wash, because it leaves you free to do what here for: be a tourist.
