The Airbnb is great and has everything you need! It is exactly as in the pictures, the balcony is even bigger than I expected. It is great that there is 24hours security at the entrance of the building and that we were able to use a safe garage.
The only negative experience we have made is that currently there are refugees camping around Greenmarket Square which is in front of the entrance. Also Long Street at night, which is very close to the apartment, for two women is not the safest area in cape town. But we used Uber when we came back late and they drove us almost in front of the entrance so it was fine for us. Positive about the location is that it is right next to a hop on hop off bus station and you have a lovely view of table mountain from the balcony.
