We can absolutely recommend staying at Caroline's place. The Green Room has its own entrance, toilet and shower but you can still use the kitchen in the house and have a little chat with Caroline and the other visitors. Caroline gave us a lot of advice of what to do and to visit in Cape Town and the area. However, it is probably more convenient if you have a car because it is about a 30 to 40 minutes drive to the city centre.
We enjoyed staying at Caroline's place a lot. Thank you for everything!
