I had an excellent stay! Orhan is a very warm and kind host. The apartment is really big and tastefully decorated. The room was also very comfortable with a door unto the balcony and windows that I left open at night for a cool breeze. The apartment was absolutely spotless. It was very central with easy access to the rest of the city. The ferries, bus to the airport and the Metro was close by.
It was a great place to stay to explore the rest of Istanbul, I loved it.
Also great value for money!
