Need Info for 2 month stay at Johannesburg ?

I along with my Daughter would be coming for aviation pilot training to Joberg in September.

While she has been given an official accommodation, I have to find one.

I am planning to stay for like 2 to 3 months to get here settled & then return home.

Can you help on how do I actually get a stay? Hotels for 3 months sounds very expensive.

What options do i have?

Location of her stay:- Sagewood Street.

Training location:- Lanceria Airport.
