What island are you talking about? It all depends. Some appartments have washers, and some students prefer to use laundry services. When I was in Dominica my appartment complex had laundry service. I'd just drop it off in AM, and they bring it to my appartment already washed and dry in the afternoon. All, of course, for a separate fee. But school are you going to? You've asked about 3 or 4 here 😕
LOL Uh on Bonaire we have a full service and self serve Laundry in the middle of town (washer and dryer), most of us live within a half mile of it. Most places have washers and dryers HUH? Its the Caribbean just hang it out it drys in hour LOL
Again where? You've asked about several schools on different islands. Oldpro may probably give you some Bonaire info. Mine used to cost 15-20 EC every week. $1=2.67 EC. Hope it helps.
