My parents stayed at Sadiks place when they came to see me in Istanbul and they absolutely loved the experience.
The location was perfect for them exploring the sights on their own because of the public transport around, the bed was comfortable, flat felt cozy. Also they hosted a friend and comfortably lived 3 of them. They cooked at home and had everything needed in the kitchen.
They recommend Sadiks place as a great spot for a calm family time and planned one more trip for Istanbul. Very grateful to Sadik for hosting my parents, it was my pleasure to see them happy and relaxed.
