Loved my stay at Wanda's. The cottage was very spacious, clean, with everything you need. The hosts were friendly and helpful whenever I needed them.
The area is safe and there are beautiful mountain views from the front of the house. Also close to my favourite beach in Cape Town, Sandy Bay (it's nude friendly if that's your cup of tea).
I'd say the accommodation is best enjoyed with a car, otherwise it can be a bit far to walk to the shops/cafés etc (maybe 20-30 mins). Overall though, great value for money.
I've stayed in lots of AirBnBs in my 2 months in Cape Town and I'd definitely return to this one if I was visiting again.
