All 1-bedroom and larger units have a washer & dryer in the villa. If you are in a studio, there is a laundry room available for use. The machines are free but you will need to buy or bring your own laundry detergent.
Yes, those washer/driers get a workout! I packed for 3 days during my most recent 10 night trip! Just came home and all I have to do is unpack...not lotsa of laundry!
I don't know what we would do without the laundry rooms. I don't like to check our luggage on the plane, so we pack with the minimum amount needed so we can bring our bags onboard. I always plan on doing laundry one night. And since they washers/dryers are free, it is perfect.
Our first few stays in studios we did laundry and I paid for it each time. Then finally learned here that the you just start the machines without the coins. I felt really stupid but one of my lessons learned.
