Yuksel is a great host, we stayed in the Amedrose house for our 5 nights in Instanbul. Since the location is in the Sultan Hamet area, restaurants, Hagia Sophia, Blue Mosque , Grand Bazaar etc. are all 8-10 mins walk away. The roads in the Sultan Ahmet area are narrow and hilly, keep your best walking shoes when going around & expect a good workout.
The view from the apartment is amazing overlooking Bosphorus, ours was on the third floor, and there is no elevator, so please be mindful of that.
There is a terrace top with seating to enjoy the sunset with a view and sipping evening tea.
The rooms are adequately sized, one bathroom does make it slightly inconvenient if you are two couples sharing the place.
