If you rent a house, the house staff will find a woman to come do your laundry, weekly or more frequently, if needed. This will cost about Q20 or $3/load. Be advised that hand washing can be hard on delicate fabrics, so you might want to give special instructions. Or, bring more durable cotton fabrics.
If you do a home stay, your laundry may be included in the cost. However, if your clothing is heavy or difficult to wash, you may be charged extra.
Dolores (5384-7441) has a laundry service. She will pick up and return your laundry.
