Two bed apartment, large living room, kitchen, utility area, in Puerto Plata, inversor but rarely needed, fridge, TV on 18 hours per day (don't ask!), electric kettle boiled 6 times a day, washing machine average 15 cycles per week, two ceiling fans running 18 hours each day except winter (but three fans running 24 hours each day in four hottest months), hot water heater in bathroom average 30 mins per day. Electricity consistently around RD$850 per month (maybe RD$1000 in hottest months?) and I am happy with that.
Wouldn't have A/C if it were free. Nasty American fetish.
