I had a great stay at Onder’s place. It was a convenient location near Taksim Square and the Hava Bus Airport Shuttle Station for a reasonable price. It was quiet at night which made it peaceful to sleep, unlike other places in touristy areas. The bed was very comfortable. Has all the amenities you need plus free tea and coffee. Onder and his flat mate were very friendly and respectful. If you want real local experience then I definitely recommend staying here.
