I lived in Madrid over winter years ago, and it dropped to -6c for a few nights. I'm from the UK so I'm somewhat used to colder temperatures (it's 0c currently for example), but my god, that is the coldest I've ever felt in my life. I went to bed dressed in 3 layers of clothes and I was still freezing.
