Ece & Aysu's place is practically the best spot to stay at in Istanbul if you want to spare no time exploring the city right away. You walk out, cross a side street and are at Karakoy. The Bosphorus lies ahead, a tram ride either way to SultanAhmet, Dolmabahce etc. The apartment is stylish, very clean and well equipped. On the ground floor, they run a little cosy coffee shop and right next doors is another artsy coffee place. Ece was very helpful and her support staff helped with directions, luggage, storage etc. Highly recommended.
