I'm sure that many users of Airbnb will be reluctant to stay in a township, but there is no excuse not to give Lydia's place a go. You will not find a more welcoming family anywhere in the world, and there is nothing to fear from the neighbourhood at all - everyone you meet says hi and welcome and shakes your hand. Graceland has brick houses and wide paved roads, and the house itself has all you'd expect from a good bed and breakfast - private room, ensuite bathroom and comfortable bed, but it is Lydia and her family that set it apart. You'll get a GREAT breakfast included in the price, and you can add dinner too if you want - this is highly recommended! Lydia is a trained chef, and you'll get a better sense of the local cuisine eating her cooking than by hunting around for equivalent restaurants in the city bowl, so get in touch with Lydia to arrange it before you go or the moment you arrive. We didn't use public transport in Cape Town, so I don't know easy it is to get there without a car, but if you do have a car, there is off-street parking in the garage.
Whether you stop by for a single night or for longer (we stayed for 3 nights), it'll be a highlight of your trip, as proven by the many many happy travellers who've written in the guestbook. She may be new to Airbnb, but Lydia's been welcoming guests into her house since before Airbnb existed, so she's a seasoned landlady. Book-in and enjoy!
