This apartment is a great base for visiting Cape Town. It's spacious, comfortable, well-equipped with all cleaning and kitchen facilities (including my personal favourite, a Nespresso), spotlessly clean and centrally-located, in a secure building. The views from the apartment are wonderful - the mountain looms above one side, and the other looks down a main street. If you're a light sleeper, bring your ear plugs, as the apartment does get some street noise at night, as you'd expect in the middle of a CBD.
Within a 5-minute easy walking radius of the building, you can reach a Woolworths supermarket and a number of restaurants and cafes, plus attractions including the Castle of Good Hope, Company's Garden, several museums, the SA art gallery, street markets and the main shopping precincts of the City Bowl. The V&A Waterfront is about a 20-minute walk away, or about R40 by Uber.
We didn't meet Dorothea, but Jaco and Don were welcoming, friendly hosts and quick to respond to our questions and offer advice. I highly recommend this apartment, and would certainly book it again if I'm lucky enough to return to Cape Town.
