If you are new to Spain or just moved to a new place, which is colder than you are used to, then you may want a heater (estufa). Yes, Costa Tropical has a mild winter, but that doesn’t mean it isn’t cold. Mild means we don’t have 2 feet of snow and the temp doesn’t drop below zero. No matter what, just having a cup of hot chocolate doesn’t always do the trick. Sometimes you need a little more to help keep you warm.
