We had a very nice stay at Stefan's place. We only had contact with him via Whats app (somebody else handed us the key), but he responded quickly and tried to help us wherever he could. It's a very cool neighbourhood to stay with some very nice restaurants (Baccini's for pizza, Cafe Paradiso, Bombay Bycicle club, Melissa's and other places on Kloof) and bars and shops (7/11 right across the street, bigger supermarket 5-10 minutes away) wihtin walking distance and everything else within (short) driving distance. The apartement has a nice balcony, it was clean and it's spacious for two persons. The kitchen has everything you need too and we never had any problems with finding a parking spot just across the street. The shower was interesting, but it worked.
If you are looking for a very luxurious place on Kloof, don't stay here, but if you are looking for a cozy place that feels like in the middle of a very nice and cool section of Cape Town, this is the place!
