The temperature inside the caves varies between 17 and 21 Cº bc during the whole year. That means it feels cool in summer and warm in winter and that makes it very agreeable to live in a cave.
The houses in the caves are dug out of the mountains. They didn´t use any construction materials; they only painted them with white chalk. Chalk is a natural paint which is porous and the air can circulate preventing humidity in the cave.
