We (2 couples) had three nights at Kim's near the V & A Waterfront, and it was pretty much as you'd expect from the surrounds and photos.
It was easy to find (the airport taxi driver knew where to take us), and we were met at the entry, eased through security procedures and shown around our unit by the lovely Thembeka.
There is a back entry (using the security tag) to the V&A Wharf, which we used all the time.
The apartment is new, modern, and well appointed with quality appliances (including a washing machine, dryer and dish washer). Both bedrooms were ensuited, and there was an extra toilet. There was a bottle of milk in the fridge, with tea, coffee and sugar, waiting for us. Communication with Kim was great throughout; she even arranged to print a letter for me.
I've stayed in hotels in Cape Town near the V & A Waterfront, but would now never stay anywhere else. So comfortable; so convenient.
