Oyster "There is a rooftop pool and sundeck with some nice views of city, though you cannot see the beach from the hotel"
Jetsetter "When you’re not shopping your heart out or seeking sand space at the nearby beach, spend your days lounging on the sun terrace by the rooftop pool or hitting the newly-opened bar for light snacks, coffee and speciality cocktails"
