This hotel, described on its website as 'super cheap but sexy-chic', was recently voted one of the 25 coolest hotels in the world by Conde Nast Traveller. It’s certainly intriguing: an ugly converted 1960s office tower block right near the train line which was opened when the actor John Malkovich, one of its shareholders, got into bed with 300 Welsh secretaries on live television. Rooms cost £45 per night for a standard room, and £85 for a penthouse.
