Everyone who thinks the sun always shines in Spain and the temperatures are always nice, please, don’t come here. Go somewhere else. Most houses have no calefaccion (heating). Some have this: a table with a cloth over it and a hole in a plank at the bottom. In the hole is supposed to go the red thing. This is a round iron box that is open on top. You put the wire in a socket and a wrought iron bar inside gets red, and hot. You’re supposed to put your feet under the cloth. Watch it because you’re bound to get burned.
