I had a long stay at Kirsten place and it is completely and highly recommended. She was super helpful and communicated efficiently and quickly on queries.
A fantastic view of the WHOLE of Table Mountain greets you every time you come in - this view alone makes it worth it and will come at a much higher price elsewhere. The location is perfect and safe with a security desk and walking distance to everything that you would want to see and do in the City Center. It has parking that is in the building and is a big plus in the city center if you have a car.
I highly recommend the Truth Jazz 50m around the corner on Thursday nights. I could just walk to the co-working facility 2 blocks away - RoamWorks. This is really the full package if you want a digital nomad experience in Cape Town.
