Everyone who thinks in Spain the sun always shines and the temperatures are always nice, 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 whire 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.
