What a solid Airbnb. Incredibly clean and spacious unit with a great view of Table Mountain, Lion's Head, and Bo Kaap. Comfy bed and all the bathroom and kitchen essentials are provided.
The binder that others have mentioned below breaks down the whole city for you so you don't even need to do any research beforehand - it tells you the best restaurants, bars, beaches, hikes, day trips, etc. Claire definitely has good tastes and everything that we did from her list was great. It's located 1-2 blocks away from the center of the De Waterkant neighborhood, which is really nice and we felt safe walking to and from that area back to the apartment at night.
The only thing I would note is that they have started construction directly across the street from the unit. As of December 2016 they are still clearing the site so it's not blocking the view - yet. I'm not sure what they are building or how tall it will be. It is quite loud however during business hours when they are doing construction. It woke us up once at 6am but I just turned the air conditioner on high and it drowned out the noise. Really the only negative thing I can think of about the experience.
