Las casas son hechas de papel

This morning I went on a nice run in the bitter cold, came back and was about to sit down for breakfast before my shower when the downstairs neighbor came buzzing at the door. Spanish people speak extremely fast when they get excited, but I did get one thing out of the conversation: el techo en su cuarto de baño se cayó. My señora went downstairs to investigate and came up murmuring "Dios mio," speaking really fast. It seems the whole ceiling of the downstairs neighbor's bathroom fell. As such, under orders from the police and common sense, we can't enter our only bathroom for fear of falling through the floor. As you might imagine, this presents a bit of a problem.
