My girlfriend and I loved our stay at the apartment. It is located on top of the Radisson Blu. The location is very central. Everything is easily reachable.
The apartment is quiet, even though it is in the center of the city. It includes access to a nice gym and a pool bar. The pool was open, despite the water crisis. Just during the day, they cover it to avoid the evaporation.
Patricia was very nice and very quick in responding to any questions.
I highly recommend the apartment. Only one thing to note: at night some of the side streets can be sketchy. This is unfortunately the case for most of Cape Town. Use an Uber or a car - even for short distances.
