There are four-posters galore, blackened beams, open fires, the occasional ghost and plenty of historic associations. Each establishment is graded by acorns instead of stars. The Close (five acorns) in Tetbury, Gloucestershire, a 400-year-old former wool merchant's home with an award-winning restaurant, has a country house style, while the ancient riverside Swan Hotel (two acorns) in Bradford-on-Avon, Wiltshire, in one of whose rooms the harsh Judge Jeffreys once held court, is more homely.
