Linda and Ian are lovely people - very friendly and helpful hosts with a wealth of knowledge about Cape Town and the Western Cape. The Nap Sack is a charming house, as the photographs show, and exceptionally well-equipped. We had a lovely three-week stay and would not hesitate to recommend it.
As some of the other reviews suggest, it's some distance to the centre of Cape Town but is ideally placed for anyone wanting to see the peninsula as well as the city. It's right by Lakeside station and the trains are very convenient and safe to use during the day. We didn't use them at night so I'd recommend taking advice on that! Ian runs an airport pickup and tour service so you could probably manage without a hire car at this property if you didn't want to drive.
