We were staying in KL for ten days and were not keen on paying hotel prices for laundry.
We found Washhouse who were able to pick up and drop off our laundry from the hotel at a very reasonable price.
They were straightforward to communicate with, as you can book online, and then they communicate via Whatsapp.
Our clothes were returned within 48 hours (as we also had to dry clean) and very impressed with the quality — fantastic and secure service.
Recommend Washhouse if you need fast and reliable quality service in KL.
