We had a wonderful stay at Guy's house. Both him and his girlfriend were really accommodating and the house was perfect for our week stay in Cape Town. You can essentially walk to any place in downtown Cape Town from there. The house has all the essentials and some more; internet was always available and there was no problems with parking if you don't mind parking on the sidewalk.
All in all, it was a wonderful experience and I wouldn't hesitate to stay there again.
