Here in Phuket it's a must have, We have in our condo it came as part of the furniture package when we bought it,
It's a deal breaker here, Dryers are not needed here,
We own a Laundry some guest come to me if they are lazy to do their own,
It was my husbands idea when we had a few properties listed on airbnb the laundry bills were huge even for here and we were not getting a good job done and things going missing.
We had an empty shop on the main road which we owned, My husband turned into a laundry so at least we could do all our own laundry and it saved a fortune every week, especially if we get many 2 or 3 day turnover.
Because of the location the business has been very successful we get lots of passing trade and tourist, You are right about Mondays being a laundry day you should see the amount we got yesterday (Monday) OMB,
The weather was on my side yesterday, no rain.
There is a resort being built right across the road from me, I might have to buy the shop next door and expand.
This is me at the end of the day
