Exact address of Chinese Embassy in Hague, Holland

I am 73 years old. When I was 5, year 1947 I travelled from Hong Kong to Holland and stayed in the embassy because my grand father was the Ambassador of Republic of China to Holland and his name was Henry K Chang.

I am planning a trip to visit Holland this June and I like to visit the embassy area to reminisce passed memory. Will you be able to check the old records of then Republic of China and let me know the exact location to enable this old me his last wish for this trip ?
