Thanks Manon and Sabata, we had a very great time at your place! They sent lots of tips in order to feel comfortable in Cape Town. The flat is amazing, the location is perfect to move easily around the city. We had to park outside with the car, but there is always someone around in order to take care of the car during the night (R10 for the night!) and during the day, you also need to pay, but it was not so expensive.
The negative point for us: the place is quite noisy during the night, especially during week-ends because there is lots of bars and disco near around.
