Location, guy at the front desk, terrace view are the best
Internet speed was 5 mbps as opposed to their claim of 100 mbps so make sure you have proper internet service on your mobile Turk cell maybe (it has eSIM that you can order even before you reach turkey)
Nothing else to complain everything was so great
Be prepared that the neighbourhood is so busy and you will hear lot of cars and people shouting in midnights which is a good things for a foreigner as it creates a safe net with flow of people all the time so many restaurants are also there be mindful that the prices could be higher in restaurants and places in this area, which I think is quite normal given that the place is in the vicinity of the main attraction in Istanbul
All in all it was a wonderful experience, internet speed could be improved
