The view is fantastic, the pool wonderful to plunge into on a hot day to cool off, but we didn't have a perfect experience for a couple of reasons.
Power Cuts. Cape Town has rolling power cuts called "load shedding". Presumably South Africans know about this, but as tourists we didn't know about this - even though we had been in Cape Town and along the garden route for two weeks, all other places we stayed must have had backup power.
It would have been really helpful to have been told that a) there are power cuts b) they are on a schedule c) how to access the schedule. The power cuts mean no cooking, no ability to open/close the security shutters, no WiFi (note there is no 4G on either MTN or Vodacom inside the house), and no lighting 3 times a day for 2.5 hours each time, this can go up on down depending on demand. We did find a few tea-light candles, but there were only candle holders for three of them and certainly not enough to light up the size of the house. Bring flashlights.
The house is clearly very popular, and would benefit from a bit of maintenance - eg the burglar alarm needs a new battery because the system totally dies 30 minutes into a power cut.
Other things: the tap water tastes earthy, so bring a filter or bottled water, and if you plan to take an Uber back from the city late at night, be aware that the drivers are a little unhappy doing so because they can't get passengers for the return ride.
