Room much much smaller.
Room clean. Bathroom clean. Not enough toiletteries available.
No drinking water. And istanbul tap water is not potable.
Day receptionist extremely anti-semetic and anti-US.
Location excellent. 5 mins from blue mosque (which means you'll wake up shaking and terrified at 6am due to the very very loud speakers for the morning prayers.
No sound proofing. You can hear someone talking softly on the street dedpite being on the third floor.
Breakfast was good with a lot of variety.
