If you are curious how a self-service laundry should not be run, this is the perfect demonstration.
Several machines were occupied by someone working there with private laundry and external jobs, while customers were effectively told they could wash only when it suited her. When I politely mentioned that one machine had stopped and I would like to use it, I was spoken to in an extremely rude and aggressive manner. I have traveled extensively, and I have never experienced anything like this in any laundromat.
The place is dirty, no detergent is provided, no customer assistance, no service — just frustration.
This is not customer service; this is a warning sign.
Tourists and locals: do yourselves a favor and choose literally any other laundromat in Marbella.
This one is a complete waste of time.
