Family-owned by the Daktylides, this beachside adult-only hotel is part of a collection of 10 boutique resorts on Mykonos. This one is a love letter to the island, a stylish and restful place of sanctuary. Here you’ll find uber cool features, such as vinyl record players and mustard yellow retro phones in bedrooms, rattan lights suspended over swimming pools, pops of monochrome and plush black daybeds. Menus forgo the standard holiday fare, in favour of bao buns, sashimi, vegan canapes and Old Fashioneds. O epitomises boho-chic and everything here is a true work of art.
