This upscale, conference-focused hotel is housed in a purpose-built complex attached to an elegant period manor house. Its exterior may jar with its elegant aristocratic neighbor, but its common areas and 197 rooms have swish and stylish interior design. The impressive grounds include a spa and a golf course, and the Cotswold's setting is undeniably picturesque. Rates are standard for this level of hotel, but if you'd prefer to lord it up in the country house, there are a handful of rooms within the manor house that can be booked through De Vere Venues Heythrop Park.
