The honest take
Book the Four Seasons Istanbul at Sultanahmet if the old city and its monuments are the point of the trip; at $885 it costs nearly three times the St. Regis but sits inside a former Ottoman prison metres from the Blue Mosque and Hagia Sophia. Book The St. Regis Istanbul if you want a five-star base in Nisantasi's shopping district, a pool, and butler service for $341 a night, with a stronger guest-rating base of 590 reviews at 9.2. Both are genuinely five-star; the gap is neighbourhood and price, not quality.
The look and the feel
Four Seasons Hotel Istanbul at Sultanahmet
The building itself is the story: a converted 19th-century Ottoman prison, its neoclassical bones kept intact around a central courtyard garden. Rooms lean into Turkish craft with kilim-inspired textiles, marble bathrooms with deep soaking tubs, and antique-referencing furniture that avoids kitsch. Seasons Restaurant sits in a glass pavilion in that courtyard, so breakfast happens under trees with minarets visible over the walls. The crowd is older, culturally motivated, here for the Old City rather than nightlife, and the whole place feels hushed, low-rise, almost monastic against the surrounding tourist crush of Sultanahmet.
Travellers who want to wake up walking distance from Hagia Sophia and the Blue Mosque and are happy to trade a pool for Ottoman atmosphere.
The St. Regis Istanbul
This is a modern high-rise tower in Nisantasi, Istanbul's upscale shopping quarter, and it reads as international five-star rather than distinctly Ottoman: original art by Turkish artists in every room softens that, but the architecture itself is contemporary glass and stone. Spago by Wolfgang Puck runs the rooftop restaurant, Petit O Bar does the evening drinks, and Iridium Spa has a proper pool, so the building is built for hanging around rather than sightseeing. Butler service around the clock and a brasserie doing modern French cuisine both signal a hotel aimed at business travellers and shoppers rather than history tourists.
Travellers who want a five-star hotel with a pool, spa and rooftop dining in a fashionable, walkable shopping district, at under half the price.
The St. Regis, for less than half the price, gives up nothing structural but does lack the pool the Four Seasons' listing implies through its spa framing — though notably it's the St. Regis that actually has the pool on paper, so what the Four Seasons gives up here, despite its price, is that amenity; otherwise the difference is address and historical setting, not facilities.
The Four Seasons is the more beautiful place to simply stand in, because a walled Ottoman courtyard under a glass pavilion cannot be replicated by any amount of contemporary polish.

“Pros: Unbeatable location for touring Sultanahmet (old town), especially for first-time visitors to the city.”

Pros: Unbeatable location for touring Sultanahmet (old town), especially for first-time visitors to the city. Exceptional staff: very attentive and friendly. Excellent restaurants--breakfast was great and dinner at Avlu was top-notch. Luxurious comfort, yet not ostentatious. The room was spacious and clean, the pillows and linens were a dream, as were the towels and bath products; the room temperature was easily
Cons: The shower pressure in our room could have been better.
