A hidden gem in Istanbul! The rooms are very spacious, clean, stylish, and functional. The two men , one of whom is always at the reception desk 24/7, are extremely hospitable and know great English, the latter of which is a rarity in Turkey. Even their cat is adorably welcoming. The only downsides are that the location is rather far from the "northern half" of Istanbul, where the Galata Tower, Dolmabahce Palace, Taksim Square, and the best local restaurants are. Also, the immediate surrounding area tends to have the heaviest traffic in the city, which made it difficult sometimes to call a taxi via the Uber app. Also, the complex is hidden on a steep hill, so you must mention "Serdivan Hotel" to taxi/Uber drivers and point out the "Serdivan" sign on the building for any hope of them finding this place.
