Pleasant small pool (properly fenced for small kids!), enough grass for lying around in the sun, incredibly pleasant living area and terrace, fantastic views, one big and one small double bedroom (both with double beds, not singles). There is no airconditioning but the house is slightly raised up and gets the breezes, so we never felt the need. Oh, and there is a charming and incredibly competent cleaner cum housekeeper.
There are three supermarkets within a few minutes walk (Woolworths, which is like M&S in the UK, Pick n Pay and OK; more coffee shops that you can shake a stick at (our favourites were Ta-da! and Hout Bay Coffee, the first more of a cafe and the second for serious coffee drinkers).
Tim, his family and house are exactly what we all hope airbnb is. Thanks!
