Wonderful flat, wonderful view. Perfect for couples. It was as big as it looked in the pictures, very nice. Be aware that the flat is on top of a mal, so you can easily buy groceries and liquor, but of course its a bit "weird/confusing" to enter/exit the flat through there. But really not a problem at all. 100% recommend.
Sea point itself is pretty chilled (Clifton beach is wonderful and around the corner), if you want "action" you need to go into the city center, there is no "nighlife" in Sea point, its super calm and cute.
