Hans' appartement is amazing. Very well located. The pool is definitely a big plus when you are coming back after a hot day in the city.
The appartement is just up on Kloof, a very animated street with a lot of good restaurants and nice places.
Everything is one UberX ride away if you don't have a car (and you should use Uber because it's so cheap over there) : Table Mountain, Waterfront, Camps Bay, Long Street, etc.
Would definitely come back!
