I had a great experience at Bianca's apartment. She is a lovely person who is always available and will give you lots of tips. The apartment is very spacious, modern and impeccably clean. The bed is comfortable, the kitchen is well-equipped, the bathroom is large, and (my favourite part) there is a lovely balcony facing East where you can sit or even have your meals with a view of Table Mountain.
The location is equally good. Inside the business quarter, many of the great restaurants in the city center are reachable by foot in under 10 minutes.
Overall I was very happy with the experience and would definitely choose again when back in Cape Town!
