My mom and I stayed at Dogans and Arzus apartment for 2 1/2 weeks and had a wonderful time. It's located in the hilly (bring good shoes) but beautiful Galata district with loads of fantastic restaurants and cafés. If you arrive at the nearby metro station, the walk to the apartment over the cobblestone pavement with a heavy suitcase can be a bit of a challenge. The apartment (and it's view to the Bosporus) took our breath away! It was clearly furnished and decorated with much love and an eye for detail. The photos really don't do it justice. It was equipped with everything we needed and more. The best thing however, as others had mentioned before, were the two hosts Arzu and Dogan. They were incredible accommodating, helpful, friendly and kind. Thanks so much for making our time in Istanbul unforgettable!
