Whistle while you work.
If you’re looking for an awesome laundry mat in NE Portland Eliot E-Mat Cafe located in the Standard Dairy on MLK.
Free Wifi, food (not free), and it looks like they have terminals and printers that you can use for a fee. Seems quiet during the day and has nice machines.
ps.
cat pukes between comfortor and blankets at 3 a.m. == need for laundry mat
