my personal advice on my experiance.
i am from up north in africa.
a great flight school at wonderboom called pretoria flying school.
the weather is good especially in the dry season for flying and even during the rains it is not bad, and one can use the rainy days for study anyways.
the instructors were great, very proffesional and always helpful, even if you wernt their student.
infact from the owner down, everyone was always ready to give you their time and answer anything you asked. they sure helped me in preparing for the big world of comm flying.
i am not sure off accomodation but am lead to believe it is not bad in that area.
airport is great, may be a bit busier now than when i was there but controllers always handled the aircraft very well.
the GFA is very close too.
i hope this helps in your decision.
enjoy it and good luck
happy landings
