"Best for: laid-back romance Set on a private beachfront on the north of Kos, Oku embodies relaxed minimalism, with hotel rooms housed in whitewashed buildings, and everything at ground level (aside from the few rooms that have two floors). Couples should book into one of the swim-up suites, where fringed hammocks hang from private terraces and overlook a pool shared with just two other rooms. A stay here feels like moving into a very chic village, where you have easy access to a spa and restaurant, and your well-dressed neighbors (adults-only) are also there to soak up the tranquillity for a few nights. Price: from about $211 per night" - Rachel Howard, Lauren Burvill
