We enjoyed our stay.
Not too far from a lovely marina area with many great restaurants.
A bit far from Istanbul proper/tourist areas etc.
Nice, modern apartment but it needs some tender loving care regarding some maintenance issues, eg, broken door frames, cracked floor boards, some more kitchen utensils needed.
Overall Neslişah Korkmaz (I presume the supervisor) had a sympathetic ear and did offer a replacement apartment but we declined due to a large number of suitcases etc to lug around.
