We arrived at some of the coldest days recorded in Malta since 1988! Accidentally we turned on the heating with the AC one night and left it on overnight. Big mistake. It cost 20 euro! So beware. Was later told the heater is powered with solar panels but with the cloudy first few days, just running the fridge and the water heater cost us 4-5 euro a day. Shocking electricity cost aside, the apartment is good for our visit. With the exceptionally cold days also meant that we couldn't use the balcony much. A pity.
