Langholmen Hotell Stockholm, Sweden

After a 250-year run as Kronohaktet Prison, which housed some of Sweden's most notorious criminals, The Langholmen Hotell, in the centre of Stockholm, has openned in 1986. The prison included the last murderer executed in Sweden, in 1910. A wine cellar that used to be the solitary-confinement cells is now a private dining room that serves candlelit dinners, and the Langholmen Restaurant is one of Stockholm's finest restaurants, serving traditional Swedish dishes. The rooms range from hostel style to luxury.

Prices start from £83 per room per night.
