If you have more than 2,000 friends on Facebook, then you can stay in one of Europe's coolest hotels for free. The luxury Nordic Light Hotel in Stockholm is now accepting large social network presence as a form of currency, and will allow people with over 2,000 friends on Facebook to stay in a room for up to seven nights - completely free of charge. The Swedish hotel charges up to £230 a night for its trendy rooms, but not if you're bit of a baller on social media. The company will also dish out free rooms to anyone with over 100,000 followers on Instagram, or 100,000 likes on a public Facebook page. Get the full story at the Mirror
