Grosvenor House, a Luxury Collection Hotel, Dubai

What the classifiers highlight

Twin 45-storey towers on Dubai Marina hold 750 rooms done in cream, beige and ashwood, most looking over the Arabian Gulf, Palm Jumeirah or the marina itself. Row on 45, British chef Jason Atherton's tasting counter, earned its own Five Stars from Forbes, while Sanara Spa spreads five hammam pools and ten treatment rooms across 17,000 square feet.
