We recently stayed at Barbara's cottage during our trip to Cape Town. Barbara was most welcoming and accommodating. She provided us with some great recommendations in and around Cape Town. It is nice that she is right on site if you need anything.
The property is in a great location - easy to head to Camp's Bay for some beach time or food or head into other areas such as City Bowl or the Gardens. Also the cottage is a few minute walk from hiking trails that can lead your around the base or to the top of Table Mountain.
The views are simply amazing at any time of the day. The cottage has really great amenities (especially a washer which was essential for the beginning of our two week vacation).
I would definitely recommend this to anyone traveling to Cape Town.
