On the beach at Marmari, on the island of Kos, OKU Kos keeps seven rooms and takes no guests under eighteen. Diving and canoe gear are kept on site, airport pick-up and drop-off are arranged directly, and the fitness room and bar are both small enough never to feel crowded. For two people who want a short stretch by the water with little left to organise once they land.
Seven rooms keep the house small enough that the beachfront, the fitness room and the bar rarely feel busy. A front desk and security run through the night, and health care professionals are available if you need one. Diving and canoeing gear is kept on site, cycling can be arranged, and breakfast comes in covered containers if you would rather carry it down to the sand than eat it at a table. Evenings run to organised entertainment for anyone who wants it, and to nothing at all for anyone who doesn't.
OKU Kos sets a minimum age of 18 in its own house rules, read on 11 August 2026. A house whose rule drops below eighteen, or stops naming an age, is taken off HUSH — how every house is checked.
The resort sits a few steps back from the water, where the beach gives way to dunes and low reed beds before the flat blue of the Aegean. From the shaded terraces the eye travels out past sun-bleached grasses to distant headlands and the small islands scattered between them. Daybeds and loungers are set out on the sand below, close enough that the sea stays part of every day.
Inside, the palette stays soft and earthen: limewashed walls, brown linen throws, jute rugs and woven baskets against cool concrete. Bespoke beds sit low beneath cane lampshades, and speakers and quiet technology are tucked in without breaking the mood. Bathrooms are carved into plaster niches stocked with robes and local amenities, made for long, slow mornings.

Asking the house for its rooms…
Stunning location, very clean, comfortable bed with nice towels and toiletries. Staff were all extremely friendly and lovely. Food was amazing with a view of sunset at dinner. Would recommend.
- Best beach I've ever been to, fantastic views into gorgeous, blue sea, clean white sand, great service, comfortable layout, although the beach beds didn't allow for flexibility to lie down on your stomach as they...

The house lists these as things to do from here. Where a line is marked off-site it is not on the property — a dive site, a trail, a stable. That mark is ours, not theirs.
The beach is on the doorstep, and diving and canoe equipment is kept on site rather than booked through a separate outfit. You walk out of the house and you are on the sand.
Breakfast is available packed in covered containers, made for eating on the sand rather than at a table - useful on a morning when the water looks better than the dining room.
A fitness centre and locker rooms sit alongside scheduled fitness classes, so a session before breakfast doesn't need any kit brought from home.
Airport pick-up and drop-off are arranged directly through the house, along with a shuttle, so the trip from the airport to the room doesn't need a separate taxi booked.
