The honest take
Both sit at 9.4 with five stars, but the Four Seasons is $127 cheaper a night and has 484 reviews behind that score against just 54 for the Peninsula, which makes its rating far less proven. The Four Seasons also offers a pet allowance and a bar the Peninsula's list doesn't carry. For a first stay in Istanbul at this level, book the Four Seasons; if Karakoy's waterfront and a newer building matter more to you than the extra track record, the Peninsula is the one to pick instead.
The look and the feel
Four Seasons Hotel Istanbul at the Bosphorus
This is a restored 19th-century Ottoman palace directly on the water, all high ceilings, gilt cornicing and marble worked into something closer to a museum than a hotel. The rooms behind the historic facade are calmer and more contemporary, but the public spaces keep the imperial scale: garden terraces stepping down to the Bosphorus, a heated outdoor pool with tanker traffic sliding past, a lobby bar meant for lingering rather than passing through. It draws an older, quieter, formal crowd who came for the palace as much as the service.
Travellers who want to sleep inside a piece of Ottoman history and don't mind a more traditional, formal atmosphere.
The Peninsula Istanbul
The Peninsula occupies a new building on the Karakoy waterfront in Beyoglu, the group's usual polish applied to a fresh construction rather than an inherited one: indoor and outdoor pools, a spa, a rooftop-style bar in Topside, and Gallada for dining, all set against the working harbour rather than a palace garden. The address puts you among Karakoy's galleries, warehouses-turned-cafes and ferry terminals instead of the more genteel Besiktas shoreline. It reads younger and more design-forward, built for a crowd that wants harbour views and contemporary rooms over inherited grandeur.
Travellers who prefer Karakoy's gallery-and-harbour energy and a purpose-built contemporary hotel over a converted palace.
The Four Seasons' facility list shows no pool or bar gap versus the Peninsula, so what the cheaper hotel gives up here is really the Peninsula's newer build and Karakoy address, not amenities; the Peninsula, for its higher price, gives up the pet allowance and lacks a listed bar advantage of its own.
The Four Seasons is the more beautiful place to actually stand in, because a 19th-century Ottoman palace garden on the Bosphorus is not something a new building, however well finished, can replicate.
