Any advice on a good School in Cairofor our two children aged 6 and 8

My wife and I will be moving to Cairo shortly and would like to have any information regarding a suitable school for our children.

Also where's the best place for a round of golf and game of tennis ?

Depends on where you live and what your Nationality is??  Most Expats live in the Maadi/Katemaya Areas, and have access to very good International Schools in the British, American, German, French, Turkish Systems including Universities.  As a Brit this is where most of our friends live and the children go to school in Maadi.  Please research on the web.  Remember that you will have to pay School Fees for education here.
