Aston was very quick to respond when we had a question. The day we arrived, I was informed that we had been upgraded to a new hotel (called Berjer something). Since I can only judge the listing based on pictures, our new "upgraded" room looked smaller than what we had reserved on Airbnb, so I'm not sure how it was an upgrade. He offered to let us change hotels after the first night, but we were already settled and didn't want to pack up. Time was already limited in Istanbul. The new hotel had very nice staff, so at least we had good service. However this posting should have mentioned how the listing might go to another hotel that you did not pick.
