Water & Electrical
The word for HOT, in Spanish, is caliente. Caliente begins with a “C”. Water faucets imported from the USA almost all have a “C” on them.
If you are from the USA, you do not need a converter for your appliances as the condo has regular 110/220 outlets. Your laptop should also work in the condo which has free wi-fi.
You may need a converter when traveling to other areas of Costa Rica.
If your Hot Water never seems to get HOT in Costa Rica, try the handle with the “C”. Note, this may change from bathroom to bathroom within the same house.
