The Scarlet Hotel
'This stylish spa is perfect for those who care about the environment and want something a bit different,' explains Anna. 'What did we love about the Scarlet? The rugged Cornish setting, the commitment to being green without compromising on luxury and, of course, the log-fired hot tubs on the edge of the cliff, looking out to sea.'Caroline is also a fan.
