We were staying in Zermatt after travelling for a few months and required a laundry without paying hotel prices.
We found this local laundry around the corner, and she was lovely. She took a full bag of laundry, and it was ready on the same day for pickup.
We got charged for the one bag which was around 20 Franc for about 2 kilos, which was better value than paying by piece at the hotel.
We were delighted with the quality of our clean clothes and the service we received.
