I chose this hotel based on the reviews which consistently described amazing service and I was not disappointed! The service you will receive here is above and beyond. The staff were incredibly helpful, even before we arrived in Turkey they were very responsive and helped me arrange an airport pickup and turkish bath reservation in advance. They provided great suggestions on places to eat nearby (365 Rooftop Mezze was one we particularly liked) and activities to do (the Sunset Bosphorus tour we booked through the hotel was well worth it, and great value for the money on a beautiful yacht). The daily breakfast buffet was the best I have ever seen, with great variety and everything you could want (coffee, turkish tea, espresso and all kinds of food). The view from the rooftop terrace is stunning. Finally, the staff from the moment wr arrived tended to our every need, were incredibly thoughtful (especially Fatih and Aykut who went out of their way to make our stay memorable).
The hotel is quiet and we got great sleep/rest. It is located next to the spice market and is a busy area in the daytime but at night becomes very quiet, and somewhat deserted but still safe, as it is located next to a large mosque (Yeni Camii). It is a 20 min walk to the sultanahmet area, which was not bad. Other options are uber or taxis, or the tram (we did not take this as it takes the same time to walk).
Overall, I am super happy with our stay. I definitely recommend this hotel!
