Does anyone know of a laundry near the PH Zurich where I can either drop off a week and a halfs worth of clothes or last resort, somewhere I can go and do the laundry? PH Zurich is in the middle of my trip and I'd rather not spend a lot of money for the hotel to wash my socks and underwear.

BTW, hotel website says "As part of our consistent efforts to improve and maintain our hotel's appearance, we will be undertaking a soft refurbishment of our guestrooms and suites between August 2 and December 15, 2010. To minimise any disturbance to our guests, we will be closing one floor section at a time during the refurbishment."
