We had a great three weeks in February/March in this apartment and really cannot fault it as a place to stay and unwind. The fittings and artwork are lovely and the beds very comfortable. Super shower too - though unfortunately for the Cape there are water restrictions on at the moment so showers were brief. The kitchen area was well enough equipped for self-catering too, with good quality dishwasher, washing machine etc.
The location to St James and Dalebrook pools were ideal to walk to (we had a 2 and 3 year old with us), as was Kalk Bay with its shops and restaurants. Satori restaurant is really close and has great food for takeout if that's your thing.
As another reviewer mentioned, the wifi is poor but once we got used to not having it we found ourselves not missing it (it was refreshing in an odd way). It may be important for overseas visitors though, as roaming fees could mount up if you do need to be permanently 'connected'.
We would definitely stay again if the opportunity arose - but have a feeling that this will be a very popular letting so availability might be an issue!
