The Spa at Grand Hyatt Istanbul

"Plus, it's got one of the best swimming pools in the center city and continues to lure expats to Spazio, its Italian restaurant"

"With 360 luxury rooms, suites, and apartments, two restaurants, a Gaia Spa & Fitness Centre, a tennis court, Turkish bath, and arguably the best pool in the city"

"The spacious marble baths, among Istanbul's largest, have large showers (with rain-forest showerheads) and deep tubs, magnifying mirrors, bottled water, scales, hair dryers, and plenty of plush towels and June Jacobs toiletries"
