Rent Discrepancy In Knightsbridge

Here's two ads for two almost identical apartments in the new Knightsbridge apartment. First one that was in the Cape Argus this morning:

CENTURY CITY KNIGHTSBRIDGENew luxury 2 bed, 2 bath. Balcony, basement
parking for 2 cars, indoor pool & gym. R4990pm.

And one from Gumtree:

Very upmarket 2 bedroom flat,2 bathrooms, 92m2, very large balcony, o/p kitchen, living room, dining area, oven hob stove, 2 secure parking bays, swimming pool,steam room, gym, health spa,jacuzzi and sauna in complex.

Basically the same right? So why is the second ad R6900/month while the one from the paper is nearly just a hair under R2000 less a month? Does that second apartment have a better view of the various construction sites and brown lagoon that surround Canal Walk?

(PS I saw a van labelled Teazers packed with bleached blondes pull out of the Villa Italia development. Make of that what you will.)
