Esh, in Costa Rica’s surf-centric Nosara, is a new resort overlooking Playa Guiones. Despite the lush, humid situation – every building is canopied in littoral rainforest – the theme here is fire (“esh” is the Hebrew word for it). Some of the self-reverential rhetoric its owners throw about to this end (are Nietzsche quotes ever, ever relevant to a boutique hotel?) belies a very attractive-looking proposition that has already garnered a Michelin key.
