First impressions
Tucked down a residential road in Mawgan Porth, the Scarlet doesn't announce itself with the pizazz and fanfare you would expect of Cornwall's much anticipated new "luxury eco-hotel". That's all part of the plan, of course. Curved wooden walls and the sea-thrift-planted roof camouflage it against the cliff, but step into reception and the Scarlet lays its five-star hand very much on the table - floor-to-ceiling windows display a breathtaking view of the beach below. Tasteful and playful art with a Cornish coastal theme brings to life open spaces. Furniture is retro 50s with a Scandinavian feel. Ergonomic and sleek, it's like walking into an art gallery.
The rooms
All 37 have a sea view and their own outdoor space in the form of a terrace or walled garden. Ours was decorated with natural wood and stone, with warm taupe and honey fabrics. Tiny rainbow tiles made the oval bath and rain shower shimmer like water - both stand open in the room and there is no curtain to draw for your modesty. You can, however, always ask your partner to retreat to what was surely my favourite feature - a secret room at the top of a spiral staircase. Just an enormous beanbag and a big window looking out to the sea.
The food
The menu has been created by Michelin star-winning local Ben Tunnicliffe and, unlike many hotel dining experiences, our evening meal felt like a real night out. Ceviche of wild halibut and line-caught sea bass with guacamole and red onion was followed by roast monkfish tail and lobster risotto. The breakfast was likewise prepared with fresh, mainly locally sourced ingredients, served in generous portions - sweet seasonal fruit salad, gorgeous homemade jam or a full English with local sausages.
The spa
The star spa feature has to be the two log-fired seaweed baths/hot tubs perched outside on the edge of the cliff, for total immerse-yourself-in-the-scenery serenity. Then there's the natural reed-filtered pool, for a one-off wild swimming experience. Inside, Ayurvedic treatments are based on a consultation to determine your dosha or body type. Interestingly there's no spa pool, as it was deemed too energy-hungry.
The verdict
Does the Scarlet live up to its aim to be "luxurious without costing the planet"? It certainly takes its pledge seriously. With measures such as grey- and rain-water harvesting, a biomass boiler, innovative insulation and ventilation and a commitment to using recyclable materials, its CO2 output is currently calculated as "73% less than that of a notional traditional building of the same size, design and geometry". However, with the cheapest room ranging from £180 off season to £270 in high season, it's an eco-treat that most green travellers will only be able to dream about from the campsite down the road.
The rate
Doubles from £180, including breakfast. Mains in the restaurant from £15. Spa treatments from £35.
