When we arrived at a sister hotel of the host to pick up the keys, we came to know that the apartment was not available. An alternate arrangement was made to accommodate in a hotel room for the first day. Later we were moved to the apartment. The location of apartment was in Sultanahmet, close to most places of interest. It was clean and the pictures on airbnb gives a good impression of the place. A sumptuous breakfast was arranged at a nearby (sister) hotel. The staff at the hotel was very friendly.
