When planning to escape your titchy houseshare, you probably don’t imagine swapping it for an underground prison cell. But then you’d be missing out on this unique place to lay your head. A few minutes’ walk from Margate Beach, Penny Rope is a former cold store that’s been transformed into a tiny prison-style cell, with two bunk beds and bars on the door. Thankfully a stay in this petite plot is a hell of a lot more luxe than it sounds. The beds are made up with 100 percent Egyptian cotton sheets, guests are allowed to leave whenever they fancy and porridge is entirely optional. From £95 a night.
