Book the Conrad Istanbul Bosphorus. It is $29 cheaper per night, rated higher (9.6 vs 9.2) across a far larger review base (4,788 vs 590), and its position above the strait gives it the view St. Regis Nisantasi cannot match from inland. The St. Regis has the stronger name and butler service, but on the numbers alone the Conrad is the smarter booking.
The St. Regis Istanbul sits in Nisantasi, the city's designer-shopping district, and plays to that address: original artwork by Turkish artists in every room, a 24-hour butler on call, and the kind of hushed, tailored formality the St. Regis brand is built on worldwide. Spago by Wolfgang Puck on the roof and the Petit O bar downstairs give it a see-and-be-seen energy rather than a scenic one. It reads as a city hotel for people who want proximity to boutiques and a concierge who remembers their coffee order, not a room with a view.
Guests who want to be embedded in Nisantasi's shopping and restaurant scene with St. Regis-level personal service.
The Conrad sits in Besiktas directly on the Bosphorus, and the whole building is organised around that water: contemporary rooms with panoramic glass looking toward the Historic Peninsula, a Summit Bar and Terrace on the 14th floor built specifically to catch the sunset over the strait, and Manzara Restaurant serving Mediterranean food with the same view laid out below it. It is a big, well-run international hotel rather than an intimate one, but the setting does the design work that interiors elsewhere have to fake.
Guests who want a Bosphorus view as the centrepiece of their stay, at a large, high-service hotel with a huge track record of satisfied guests.
Neither hotel lists facilities the other lacks, so this comes down to address, scale and service style rather than missing amenities: the St. Regis trades the water view for a boutique-district location and its signature butler service.
The Conrad is the more beautiful place to actually be, simply because the Bosphorus is doing the work no interior designer can match, and its rooms and terraces are built to face it.

“Okan and Xavier, both you went extra mile.”
Conrad guests report happier stays, repeatedly praising standout staff by name, the executive lounge and views, while The St. Regis reviews contain no written detail to judge.
“Great one day stay in Istanbul”
The front desk staff was extremely helpful. We booked two rooms for our family of four. As Diamond members, our rooms were upgraded - one to a suite and one to a sliver Boshporus view. Both were very much appreciated. We did have to request our keys be granted access to the Executive Lounge (that's not automatic). The lounge was excellent. Breakfast was good, but the view is phenomenal. Just be careful sitting out
