We have stayed at Sokullapasa each year for the past 4 years. It really is like coming home. Clean well equipped rooms. Nothing is ever too much trouble for the staff. Walking distance to all Sultanahmet historical sites and transport. Excellent restaurant. This year we were late booking so tried another recommended hotel, we did not last one night. The Sokullupasa staff managed to find a smaller room than usual for us which was perfect. They even offered to collect and transfer our bags at no charge.
As we are in Istanbul every year we will never stay anywhere else !!!!!!
