This place was close to perfect (we lived here for 1,5 months). I would give it 4,9 Stars.
Mark and his partner are very responsive and nice and deal with all occurring problems quite fast. He and his family live below and next to the apartment so either he or his housekeeper are easily contactable almost all the time. The interior is beautiful and well maintained, the view is magnificent and the location is very good for all the things you wanna do in and around Cape Town (just don't walk around at night, but that is the case for most of Cape Town). You will always get an Uber within a minute.
There are only two things that might diminish the awesomeness:
*Heat:
The apartment has no A/C (as is indicated by the accurate description here on AirBnB). During the summer the tiles/concrete can heat up immensely. We suggested to Mark via AirBnB after our stay, that they should get sunblocking curtains which they have in the bedroom for the living area as well, which I assume they will take into consideration. This should solve most of the heat issues. Just draw the curtains during the day and open the awesome window front in the afternoon.
*Noise:
This apartment lies in the very center of a city, hence a normal amount of inner city noise is to be expected. It is, however, on the top floor. So most of the time you are not affected by it. BUT, due to the mentioned heat issue, at times you wanna keep the windows open during the night and then you might be annoyed by loud motorcycles, honking or screaming kids (especially in the morning). We however thought, that the noise levels were bearable 95% of the time and way better than at another apartment we had rented in Strand Street.
