Room was clean. Central location to Blue Mosque, Hagia Sofia and Topkapi. Front desk people were quite helpful.
The 3rd bed in our room was a pull out sofa which was not comfortable - springs were poking through at several places. The bathtub had a jacuzzi that didn’t work; Breakfast was fine; If you are a vegetarian, you have cereal, bread, cheese, tomatoes, cucumbers and watermelon. Coffee was definitely not the “Turkish” type.
BTW, Hippodrome and Azade hotels are one and the same. We had booked with Hippodrome; stayed at Azade!
