We absolutely loved our stay at Andrew's place. Cleanliness and check in were spot-on and communication from our hosts was great! We stayed for around 6 weeks and any time we needed anything from our host it was dealt with immediately.
The apartment get's beautiful light in the morning. And the with views of Signal Hill in one direction and the sea in the other, it made for peaceful breakfasts, basking in the sun on the balcony. The apartment is also really spacious and the kitchen has everything you could ever wish for - including a great coffee machine and french press! There are some fantastic books on the shelves also - try Trevor Noah's "Born a Crime"! :)
The internet is reliable and, although not exceptionally fast, you can stream, have video calls, and send files fairly quickly - my partner and I both "work from home" and rarely had any issues.
There's plenty of shops close by - and 15 minutes down Regent's Road there is a great gym called BUC fitness, which is fantastic. There is also an abundance of coffee shops, restaurants and other gyms in the area. The Sea Point area is one of the safest in Cape Town, so safety concerns whilst walking around was never a problem.
You can also walk straight out the door and up Signal Hill for a reasonably mild hike and even walk straight up to Lions Head if you're feeling like a challenge.
All in all, we couldn't ask for much more from an Air B'n'B.
