Oksana's place is located in a cool neighborhood (Waterkant/Green Point) and within easy walking distance to the downtown and business districts -- bonus points - if you ever need a rental car, there is one right in the apartment building!!
The apartment itself was very spacious and had all the necessary amenities. Caution though -- if you stay there during the Cape Town Winter months, it can get pretty cold in the apartment (there's only one portable heating source, and its not powerful enough to warm up the living room area).
Another bit of warning I would provide to would be residents is that it is not for light sleepers. Even though the apt is on the 11th floor, you can hear ALL the noise coming from the street level (including the bar on the ground floor of the building). I already mentioned to Oksana about getting double-glazed sliding doors to filter out some of the street level noise, so hopefully you'll have better luck sleeping :-)
All in all, if you're looking for convenience and easy access to all the local spots and business/financial centers, you really can't beat the location of her apartment.
