Our stay in Bo-Kaap was really lovely. The place is in a great area, with great restaurants really close by. If you are on a budget and looking to cook your meals, there is not really enough space. We managed to make cereal breakfasts though (the bowls are very tiny, but that just means having a second bowl instead of just one!). I would recommend just eating out for lunch and dinner, the restaurants in the area are really amazing.
Mansoor is friendly when present but also absent when needed which is a great quality in a host. Security is good and you have your own and set of keys.
