For almost half a century in the pages of Frommer’s, the Wardonia, in a brown-brick Georgian building, has been suggested for those times when you need a place to be super cheap, no matter the sacrifice: Rooms are wee—like sooooo tiny, as if the walls and the bed are in a deathmatch for dominance, recalling the compactor scene in Star Wars. Thus warned, you will now be prepared for the impossible value. Very simple in plain brown wainscoting,rooms have bathroom cubbies with showers but not tubs, and you don’t get breakfast—all reflected in the crazy low rates, which have barely budged in a decade. The Wardonia is one of London’s last “they’re charging how much?” crash pads.
