I stayed 1 night in Sultan's Inn in August'15.
+ The best things about this property is its location (walking distance to Blue Mosque, Hagia Sophia)
+ Good and tasty breakfast and terrace with a nice view.
+ Also, they offer free water and tea for guests, which is especialy good in hot summer day.

- The view from the window was on the wall :)
- The door of shower cabin did not close properly, so we had to wipe water from the floor after taking shower.
