If you have a place for a washing machine the service I recommend is Samsung full automatic (mine was 7 kg). All washing was done on site, choice of smell according to what brand soap I bought. Open 24 hours a day. One time fee of 11k pesos. The smaller sachets of soap were just the right size and fairly cheap at Hypermart Duma.
Some people recommend the LG because they claim it spins more water out in the spin cycle and the clothing dries faster but I can neither confirm or deny. I can confirm that the one time fee for the LG is higher.
