Accommodation
Delegates are responsible for their own arrangements.
There are numerous bed-and-breakfast places (Guesthouses) near UJ (Melville, Auckland Park, and surrounds ).
Here are few suggestions.
Another possibility is to check at Airbnb or Lekke Slaap.
Student accommodation: TBC
Safety
Walking alone in Johannesburg, off campus is not recommended. The university surrounds are normally safe and well populated with students but precautions should always be taken.
Uber is available and daily commutes from Melville to UJ should be R20 - R40 and take less than 10 minutes.
