Words cannot do justice to how perfect Karin's apartment was and how excellent a host she is.
The apartment is beautiful, spacious and extremely secure. The outdoor space is a lovely spot to have breakfast before heading out to explore the sights of Cape Town; and the location is perfect for this, a short taxi ride from the centre of town and an even shorter drive to Lion's Head (a great hike) and Table Mountain (where the cable car and views are spectacular).
The flat is furnished in extremely good taste, and is nicer than pretty much every hotel room I've stayed in. The bathroom is probably the nicest I've seen anywhere, whose centrepiece is a double shower. We had some friends round one night who'd been in Cape Town for a few months, and they said it's the nicest place they've seen in all that time.
Karin is an extremely attentive host, doing everything from stocking up the fridge before our arrival to offering us spaghetti bolognese one night (which we only turned down because of another great perk of the place - its proximity to the waterfront at Camps Bay, which has a fantastic selection of restaurants and bars that will keep you busy for days).
In short, if you're looking for a relaxing place to come back to between a day exploring the city and an evening of great food and drink by the sea, you can't do better than this.
