If you are able to give up a couple of hours at your time there's a self-service laundry that we always use a couple of minutes walk away. Come out of the hotel, turn right, cross the road, and take the first left down Soi Than Tawan. Take the first right next to Mango Tree restaurant and then the first left into a small alley and you cannot miss the self-service laundry. The hotel next door will change your notes for the coins required by the machines. The self-service laundry is here.

We always use this place and go immediately after breakfast while the day is still fresh. You can leave your stuff in the machines while being washed or dried and go get coffee. Or maybe go there first thing, return to LeM for breakfast in Latest Recipe, and then go back. It's only a couple of minutes away.
