The Capital Villa was a great place for for my family to stay, having 2 bedrooms, both with King beds, separated by a spacious living area with 2 full bathrooms. The kitchen was better than most self catering apartments with all the basics for a family of 4. Breakfast was available near reception. Security was good with the gate manned 24/7, although a con artist could probably get in without too much trouble. The receptionist was very professional and helpful.
On the downside, the apartments are surrounded by construction at the moment, making walking to the nearby Sandton Mall more difficult than usual and feel dangerous after dark. There are no backup generators, so we sat in the dark when the area lost power for a few hours as part of South Africa's load shedding.
