A boutique hotel inside a marina club at 11 Cove Drive, ONE°15 Marina Sentosa Cove holds 26 rooms and suites in the residential enclave of Sentosa Cove. The setting is quiet rather than showy, with sea breezes off the water and the city kept at a distance. It suits couples, families and longer stays alike. The marina below has been named International Marina of the Year three times and entered the Hall of Fame in 2025.

All 26 rooms and suites carry a Nespresso machine, a 49 inch smart television with cable channels and a sunken bathtub with a 14 inch screen set into it. Marina View and Marina Family categories open onto a private balcony, while the Hillview sits under a sunroof above the tub. Interconnecting rooms can be arranged in most categories, and the Monte Carlo suites add a minibar stocked for arrival.

Swimming and the gym aside, tennis and pickleball run from seven in the morning until ten at night across two courts each. Children have an air conditioned playroom, an outdoor playground and an arcade spread across level one. Bicycles can be hired, yacht charter is arranged through the club, and boaters socials and cruising trips to Nirup Island run through the year.

An infinity pool sits on level one with marina views, a wading pool and a jacuzzi alongside, open from seven in the morning until nine at night. ONE Fitness Centre runs around the clock across a gym, a studio and a Recovery Room holding an infrared sauna and an ice bath. A steam room sits in the level one changing rooms, and two tennis courts and two pickleball courts face the club entrance.

Latitude Restaurant works Asian and continental cooking from seven in the morning, with private rooms set off the main floor. WOK°15 Kitchen turns out Cantonese plates and dim sum at lunch and dinner from Tuesday onwards. Boaters Bar is the only floating bar in Singapore, grilling dockside plates from five in the evening, and HELIOS°93 covers ready to go meals through the day.

Sentosa Cove is a residential enclave, so the rest of the island and its attractions sit a short ride away with the city centre close behind. A complimentary shuttle runs for same day dining reservations. Singapore stays warm and humid through the year, which keeps the pool deck and the terraces busy. Event space and private dining rooms handle celebrations.
