Hidden gem is right. This apartment is a great find. Very clean, beds are comfortable, stylish and efficient design, and the really large and nice garden space make this flat a really enjoyable place to stay. The location is also really great and central for easily exploring the center of Istanbul, along with easy access for getting to the ferries and other public transit to get around the city. Emir was a great host, he had great communication making check-in really easy. He was very flexible to work with as my arrival time changed at the last minute on the day of arrival. The house also had many books, maps, and lists of recommendations of things to do and see in the area which was nice. We will definitely be staying here again.
