Laundry service in Warsaw, Poland
 

Is there anything like a coin laundry in Warsaw or a wash and fold service for travelers?
What about dry cleaning establishments?

Where are you staying? Hotels often offer laundry service.

I've seen coin-op laundry mats, but I don't remember where they are. I think you can inquire of the city tourist service as to their location. Dry cleaners are often found in the large supermarkets, but I've seen stand alone cleaners, too. Again, look near the large modern corporate offices.
